Answer:

C. Cos(28) = \frac{15}{17}

Step-by-step explanation:

Recall: SOHCAHTOA

Thus,

Cos(\theta) = \frac{Adjacent}{Hypotenuse}

Reference angle = 28°

Adjacent = 15

Hypotenuse = 17

Plug in the values

Cos(28) = \frac{15}{17}

xxMikexx [17]
Supplementay means adds to 180
x and y could be 100 and 80
x and y could be 1 and 179

acute means that it is less than 90


since we are not told what x or y is, y could or could not be acute
