Question

If angle A has a measure of 115 degrees, find the measure of angle C. Then If angle B has a measure of 34 degrees, find the measure of angle C.

Answer 1

Given,

∠A = 115°

∠B = 34°

∠C = ?

To Find,

Measure of angle C.

Solution,

We know that

In a triangle, sum of all angles is 180°.

Also, we have

∠A = 115°

∠B = 34°

=> 180° = ∠A + ∠B + ∠C

By substituting, we get

180° = 115° + 34° + ∠C

=> ∠C = 180° - 149°

=> ∠C = 31°

Hence, measure of ∠C is 31°.

Answer 2

Given: Here we have given

A=115 degrees

B=34 degrees

C=?

To find: we have to find the angle C

Solution:

We all know that the sum of angles of traingle is 180 degrees

so,

$C=180-(A+B)\\\\=180-(115+34)\\\\=180-149\\=31 degrees$

Final answer:

Hence the answer is 31 Degrees
