The inside angles of a triangle always add up to 180. So, if you add the two angles you do have (105 + 34 = 139), you can find out the third:
180 - 139 = 41

What is the third angle of a triangle if the other angles are 48 and 29?
As the sum of angles is a triangle is 180°, the third angle is 180-48-19=103°
Has an isosceles triangle have an obtuse angle?
Not necessarily. The two equal angles in an isosceles triangle must both be acute angles. If they were right angles or obtuse angles then a triangle could not be formed. If the two equal angles are less than 45° each then the third angle is an obtuse angle. If they are both 45° then the third angle is a right angle and if they are both greater than 45° then the third angle is an acute angle.
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
How do you determine the third angle of a right triangle if 2 angles are known?
simple... first we know that a triangle has a sum of 180 degrees therefore you add the two known angles then subtract their sum from 180 which gives you the measure of the third angle
If two angles in a triangle are 35 what is the third angle?
110
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).
The sum of the first two angles of a triangle are twice the measure of the third angle The first angle is half of the second angle What are the three angles?
The angles are 40, 80 and 60 degrees.
If two angles of a triangle are copmplimentary what is the measure of the third angle?
Two angles of a triangle add up to 65°. What is the measure of the third angle?
If two angles of a triangle each measure what is the measure of the third angle?
180- total of the first two angles= 3rd angle
What is the third angle of a triangle if the other angles are 48 and 29?
As the sum of angles is a triangle is 180°, the third angle is 180-48-19=103°
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.
If two angles of a triangle each measure 54 What is the measure of the third angle?
If two angles of a triangle each measure 55 what is the measure of the third angle?
What is the Third angle theorem?
If two angles of one triangle are congruent to two angles of another triangle, then the third angles are also congruent.
Has an isosceles triangle have an obtuse angle?
Not necessarily. The two equal angles in an isosceles triangle must both be acute angles. If they were right angles or obtuse angles then a triangle could not be formed. If the two equal angles are less than 45° each then the third angle is an obtuse angle. If they are both 45° then the third angle is a right angle and if they are both greater than 45° then the third angle is an acute angle.
What is the angle opposite the base angles of an isosceles triangle?
The third angle of an isosceles triangle doesn't have a name.
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
How do you determine the third angle of a right triangle if 2 angles are known?
simple... first we know that a triangle has a sum of 180 degrees therefore you add the two known angles then subtract their sum from 180 which gives you the measure of the third angle
