Question

Can someone plz help me

Answer 1

A = 65, B = 75

Explanation:

x + x + 10 + 40 = 180

2x + 50 = 180

2x= 130

x = 65

Answer 2

∠A = 65°

∠B = 75°

Explanation:

The sum of all the angles in a triangle is 180°, so we need to add all of the angles and make them equal to 180, then solve for "x".

x + x + 10 + 40 = 180

2x + 50 = 180

2x = 130

x = 65

Now, we replace "x" with 65 to get ∠A and ∠B.

∠A = x = 65°

∠B = x + 10 = 65 + 10 = 75°
