Hello :
x² -x -56 = <span>(x + 7)(x - 8)
because : </span><span>(x + 7)(x - 8) = x² - 8x +7x - 56
= x² -x -56</span>
Answer:
877.419 , 877.078 , 836.219
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
Since we know the measure of ∠B and the side opposite to ∠B and we want to find BC, which is adjacent to ∠B, we can use the tangent ratio. Recall that:
The angle is 54°, the opposite side measures 16 units, and the adjacent side is BC. Substitute:
Solve for BC. We can take the reciprocal of both sides:
Multiply:
Use a calculator. Hence:
BC measures approximately 11.62 units.
Our answer is B.
