Question

find the lettered angle in each of the following​

Answer 1

Answer:

X =76°

Step-by-step explanation:

because opposite angles are equal

Answer 2

Answer

∠C=76

∠A = ∠B

∠A+∠B+∠C=180

x+x+76=180

2x=180-76 = 104

x=104divided by 2

= 52

∠A=52 ∠B= 52

∠1 +∠2+∠3=180{linear pair axiom}

76+52+53=180

X=52 + 76 {ALT INTERIOR ANGLE}

x= 128
