Plz which choice is the approximate measure of a-64.80 b-61.93 c-28.07 d-25.20

D. 25.20

Step-by-step explanation:

This looks like a SohCahToa problem. This method is used for finding missing angles and sides of right triangles. It stands for:

Sine: opposite/hypotenuse

Cosine: Adjacent/hypotenuse

Tangent: Opposite/Adjacent

In this case we need to use Tangent to find angle E since we have the opposite (8) and the Adjacent (17). To find angles, you must use the inverse of Tan this time.

Tan^-1 = 8/17       (plug into your calculator *make sure it is in degree mode*)

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
