Answer:
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
∠ AOC = 90° and
∠ AOB + ∠ BOC = ∠ AOC , that is
x + 8 + 2x = 90
3x + 8 = 90 ( subtract 8 from both sides )
3x = 82 ( divide both sides by 3 )
x = 
Then
∠ BOC = 2x = 2 × = 
≈ 54.67° ( to 2 dec. places )

32.6 = 17.3 + -1d
Solving
32.6 = 17.3 + -1d
Solving for variable 'd'.
Move all terms containing d to the left, all other terms to the right.
Add 'd' to each side of the equation.
32.6 + d = 17.3 + -1d + d
Combine like terms: -1d + d = 0
32.6 + d = 17.3 + 0
32.6 + d = 17.3
Add '-32.6' to each side of the equation.
32.6 + -32.6 + d = 17.3 + -32.6
Combine like terms: 32.6 + -32.6 = 0.0
0.0 + d = 17.3 + -32.6
d = 17.3 + -32.6
Combine like terms: 17.3 + -32.6 = -15.3
d = -15.3
Simplifying
d = -15.3</span>
