Answer:
16.2
Step-by-step explanation:
A trick to remember for right triangles is SOH-CAH-TOA:
Sine = Opposite / Hypotenuse
Cosine = Adjacent / Hypotenuse
Tangent = Opposite / Adjacent
Here, we have the side adjacent to the angle and the hypotenuse. So we should use cosine.
cos 22° = 15 / x
x = 15 / cos 22°
x ≈ 16.2
Answer:
399.30
Step-by-step explanation:
12.10 times 33 hours equals 399.30
Answer:
C
Step-by-step explanation:
This is because in order to find the area, you need to dfine R^2*PI and half of 12 is 6 so 6*6 is 36 and 36 times 3.14 is 113.04 and since you need to convert it into cal, times that by 22 which is C
Although the equation didn't come out right, yes when two number are covered in parenthesis it means to multiply them
E.g. (2)(2) or (1/2)(1/2)
