In plane geometry the angles in a triangle always add to 180 degrees. Add the two angles you know together and subtract the total from 180. This will give you the third angle.
70 + 65 = 135.
180 - 135 = 45

If the measure of one angle of a triangle is 10 degrees more than the smallest angle The Measure of the third angle is 50 degrees more than the smallest Find the three angles?
The three angles are 40, 50 and 90 degrees.
Find the third angle of a right triangle if the measure of on of the angles is 68?
The sum of interior angles of any triangle is 180 degrees. A right triangle is defined as a triangle having one angle that measures 90 degrees. Therefore, it follows that the sum of the remaining two angles will be 90 degrees 90-68=22 The third angle is 22 degrees
What angle is twice the measure of its supplement and Find the measure of the two supplementary angles?
60 degrees and 120 degrees
The second angle in a triangle is four times as large as the first The measure of the third angle is 80 degrees more than sum of the other two angles. Find the measure of the second angle?
Let the first angle be x the second angle be 4x and the third angle be 80+4x+x: x+4x+80+4x+x = 180 Collect like terms: 10x = 180-80 10x = 100 x = 10 Therefore the measure of the second angle is 40 degrees.
What is the measure of an angle supplementary to an angle that measures 101 degrees?
Supplementary angles are angles that add up to 180 degrees, ie. a straight angle. Therefore, the angle supplementary to 101 degrees would be 180-101=79 degrees.
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
If the measure of one angle of a triangle is 10 degrees more than the smallest angle The Measure of the third angle is 50 degrees more than the smallest Find the three angles?
The three angles are 40, 50 and 90 degrees.
Find the measure of angle abd if the measure of angle dbc is 16 degrees and the measure of angle abc is 89 degrees?
The measurement of angle ABD is 73 degrees. You find this angle by subtracting angle DBC from angle ABC, or 89-16 is equal to 73 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.
The measure of the second angle in a triangle is five less than the first. The third angle is thirteen more than twice the first. Find the measure of each angle?
The angles are: 43 degrees. 38 degrees and 99 degrees which all add up to 180 degrees
The second angle in a triangle is one third as large as the first the third angle is two thirds as large as the first angle find the angle measures?
Let's assume the measure of the first angle is x degrees. The second angle is one-third as large as the first, so its measure is (1/3) * x = x/3 degrees. The third angle is two-thirds as large as the first, so its measure is (2/3) * x = 2x/3 degrees. Therefore, the measures of the angles in the triangle are x degrees, x/3 degrees, and 2x/3 degrees.
The measure of an angle is 20 less than 3 times its supplement find the measure of the angle?
40-degrees 140-degrees
How do you find the angle degrees?
A protractor is nused to measure angles in degrees.
If Two angle measurements in a triangle are 35 and 77 Explain how to find the third angle measure in the triangle?
The sum of the three angles of a triangle will always be 180 degrees. So to find the third angle, one must take 180 - 35 - 77. The answer would be 68
what- Find the measure of the angle shown, in degrees.?
78
Find the third angle of a right triangle if the measure of on of the angles is 68?
The sum of interior angles of any triangle is 180 degrees. A right triangle is defined as a triangle having one angle that measures 90 degrees. Therefore, it follows that the sum of the remaining two angles will be 90 degrees 90-68=22 The third angle is 22 degrees
