HELP PLEASE! Isosceles triangle ABC is shown below.
Triangle A B C. Angles B and C are x. Sides C A and B A extend to form an exterior angle at point A with a measure of 22 degrees.

What is the value of x?
22°
79°
136°
158°

x = 79°

Step-by-step explanation:

→ Remember that vertically opposite angles are equal so 22° is opposite to CAB so angle CAB is 22°

CAB = 22°

→ Remember the fact that

Using the information we form an equation,

2x + 22 = 180

→ Minus 22 from both sides to isolate 2x

2x = 158

→ Divide both sides by 2 to isolate x

x = 79°

what is the model?
