Answer: ∠B=70°
Step-by-step explanation:
It is shown in the diagram that ∠A and ∠B is vertical angles.
- Vertical angle theorem: opposite angles are congruent.
<u>Solve:</u>
∠A=∠B
8x+6=4x+38
4x=32
x=8
<h2>∠B=4x+38=4(8)+38=32+38=70°</h2>

Answer:
x = y^2 + 4y + 3
Step-by-step explanation:
f(x) = ( x + 2 )^2 - 1
y = ( x + 2 ) ^ 2 - 1
y = ( x^2 + 4x + 4 ) - 1
y = x^2 + 4x + 4 - 1
y = x^2 + 4x + 3
x = y^2 + 4y + 3
(switch from y to x and x to y)
I hope that helps!
