If Cos theta = 15/17, then
Sec theta = 17/15 because cosine and secant are reciprocal functions.
Letter A
Answer:
∠2 = 152
Step-by-step explanation:
A straight angle should always equal 180, and that is really the key to how we answer this problem. That means that ∠1 and ∠2 are supplementary, and add up to 180°.
That means that 180-28, will give us our other angle.
The formula is A= 4(pi)r*squared* 201.06
