Question

Find the measure of each labeled angle.first,find x=……..,m(angle)A=……,m(angle)B=…..,m(angle)C=……..

Answer 1

x=40 m∠A=100° m∠B=80° m∠C=65°

Explanation:

Step 1: Find relationships between the angles (corresponding, alternate exterior, alternate interior, consecutive interior, or consecutive exterior)

Step 2: m∠A + m∠B = 180°

So, (3x-20)° + (2x)° = 180°

Step 3: Solve for x (x=40)

Step 4: Plug in x to the angles

m∠A= 3(40) - 20

m∠B= 2(40)

m∠C= 2(40)-15

Answer 2

24

Explanation:

you slove the sides and find x
