Question

Find the measure of m∠A (inside the triangle).

Find the measure of m∠B.

Find the measure of m∠C.

Answer 1

m<A=40°

m<B=55°

m<C=85°

Explanation:

Add up all the angles to equal 180 because all triangles add up to 180.

(2x+5)+(x+15)+x=180

Simplify.

4x+20=180

Solve for x.

x=40.

Plug x into the equations. Hope this helps.
