Answer:
x = 11.8639
Step-by-step explanation:
cos∅ = adjacent / hypotenuse
Since we are dealing with right triangles, we can use trig to help solve for missing values:
cos22° = 11/x
xcos22° = 11
x = 11/cos22°
x = 11.8639
Answer:
The answer is D) 4, 8, 12, 16, 20
Step-by-step explanation:
X^2 - 2x - 8 = <span>(x + 2)(x - 4)
</span>reciprocal of x^2 - 2x - 8 = 1 / [(x + 2)(x - 4)]
<span>
answer is </span><span>C. 1 / [ (x + 2)(x - 4) ]</span>
