Answer:
∠ B = 70°
Step-by-step explanation:
A and B are alternate exterior angles and congruent, that is
∠ A = ∠ B , substitute values
8x + 6 = 4x + 38 ( subtract 4x from both sides )
4x + 6 = 38 ( subtract 6 from both sides )
4x = 32 ( divide both sides by 4 )
x = 8
Thus
∠ B = 4x + 38 = 4(8) + 38 = 32 + 38 = 70°
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>
