A triangle has one angle of 80 degrees an another of 60 degrees how many degrees must there be in the third angle?
The sum of the angles of a triangle is 180 degrees. So we have: 80 + 60 = 140 degrees, the sum of the two angles of the triangle 180 - 140 = 40 degrees, the measure of the third angle. Thus the measure of the third angle is 40 degrees.
What is the measure of the third angle of a triangle if one angle measures 15 degrees and the other measures 85 degrees?
The sum of the measures of the angles of a triangle is 180 degrees. First, calculate the sum of the two known angles. Then subtract that result from 180. That difference is the measure of the third unknown angle. Given: One angle of a triangle is 15 degrees and the second angle of the triangle is 85 degrees. To find: We need to find the third angle of the triangle. Let the third angle of the triangle be x. We know that the sum of the angles in a triangle is 180 degrees. ==> 15 degrees + 85 degrees + x degrees = 180 degrees. ==> 100 degrees + x degrees = 180 degress. ==> x = 180 degrees - 100 degrees. ==> x = 80 degress. Therefore the third angle of the triangle is 80 degrees.
Interior angles of a triangle are 50 degrees and 60 degrees. What is the third angle?
The sum of the three internal angles of a triangle is equal to 180 degrees. Since the two known angles are 50 degrees and 60 degrees, the third angle is equal to 180 - 50 - 60 = 70 degrees.
In a right triangle there is a 57 degrees angle. What is the measure if the third angle?
Remember in a right angles triangle, the right angle is 90 dgrees. The sum of the three angles in a triangle is 180 degrees. Hence x + 57 + 90 = 180 x + 147 = 180 Subtract 147 from boths sides x = 33 degrees.
If two angles of a triangle each measure 54 What is the measure of the third angle?
Well, honey, the sum of all angles in a triangle is 180 degrees. So if two angles are already 54 degrees each, the third angle would be 72 degrees to make up the total. It's basic math, darling.
The sum of the measure of two angles of a triangle is 95 degrees What is the measure of the third angle?
The third angle is 85 degrees. The sum of all internal angles in a triangle is always 180 degrees
What is a triangle with angles of 60 degrees and 30 degrees?
The third angle has to be 90 degrees so it would be a right angle triangle.
If two angles of a triangle are complementary what is the measure of the third angle?
If two angles of a triangle are complementary, it means they add up to 90 degrees. Since the sum of the angles in a triangle is always 180 degrees, the third angle would be 180 degrees minus 90 degrees, which equals 90 degrees. Therefore, the measure of the third angle in this triangle would be 90 degrees.
What is the third angle of a triangle if the sum of the other two angles is 148 degrees?
The sum of the angles of a triangle is 180 degrees. If the sum of two of a triangle's angles is 148, then the third angle must be 180 - 148 = 32 degrees.
How do you determine the third angle of a triangle if 2 angles are known?
There are 180 degrees in a triangle. So, if you subtract two angles (angles A and B) from 180 degrees, you get the third angle (angle C). So: 180 - A - B = C
A triangle has one angle of 80 degrees an another of 60 degrees how many degrees must there be in the third angle?
The sum of the angles of a triangle is 180 degrees. So we have: 80 + 60 = 140 degrees, the sum of the two angles of the triangle 180 - 140 = 40 degrees, the measure of the third angle. Thus the measure of the third angle is 40 degrees.
What if two angles of a triangle are complemenatr what is the measure of the third angle?
The sum of two complementary angles is 90 degrees. The three angles of a triangle add up to 180 degrees. Hence, if you subtract the complementary angles from 180, you have the measure of the third angle: 180 - 90 = 90 (this is the third angle) As a rule, if two angles of a triangle are complementary, the third angle is a right angle (90 deg). The three angles together form a right triangle.
The measure in a third angle in a triangle with angle in a triangle with angles of 39 and 77 degrees is.?
180-39-77 = 64 degrees
What is the measure of the third angle of the triangle?
The third angle of a triangle is equal to 180 degrees minus (the sum of the first two angles).
Two angles of a triangle have measures of 59 degrees and 28 degrees. find the measure of the third angle.?
The third angle is 93 degrees
What is the measure of the third angle of a triangle if one angle measures 15 degrees and the other measures 85 degrees?
The sum of the measures of the angles of a triangle is 180 degrees. First, calculate the sum of the two known angles. Then subtract that result from 180. That difference is the measure of the third unknown angle. Given: One angle of a triangle is 15 degrees and the second angle of the triangle is 85 degrees. To find: We need to find the third angle of the triangle. Let the third angle of the triangle be x. We know that the sum of the angles in a triangle is 180 degrees. ==> 15 degrees + 85 degrees + x degrees = 180 degrees. ==> 100 degrees + x degrees = 180 degress. ==> x = 180 degrees - 100 degrees. ==> x = 80 degress. Therefore the third angle of the triangle is 80 degrees.
Two angles of a triangle measure 45 degrees and 60 degrees what is the measure of the third angle?
The third angle is 75 degrees. The 3 angles of a triangle add up to 180 degrees. Therefore: 45 + 60 + 75 = 180.
