Question

What is the measure of angle c

Answer 1

Answer:

C. $70^{\circ}$

Step-by-step explanation:

We have been given an image of a triangle and we re asked to find the measure of angle C.

Angle sum property of triangles states that all angles of a triangle add up-to 180 degrees, so we can set an equation as:

$m\angle A+m\angle B+m\angle C=180^{\circ}$

Upon substituting the given measure of angle A and B in our equation we will get,

$70^{\circ}+40^{\circ}+m\angle C=180^{\circ}$

$110^{\circ}+m\angle C=180^{\circ}$

$110^{\circ}-110^{\circ}+m\angle C=180^{\circ}-110^{\circ}$

$m\angle C=70^{\circ}$

Therefore, the measure of angle C is 70 degrees and option C is the correct choice.

Answer 2

C is the correct answer because triangles always equal to 180 degrees
