For this right triangle, what is the cosine of angle C?
A)
12
13
B)
13
12
C)
5
12
D)
5
13
E)
13
5

A

Step-by-step explanation:

In this triangle hypotenuse=13

And perp=5

Now

Finding base

Hypotenuse^2=base^2+perp^2

(13)^2=base^2+(5)^2

169=base^2+25

Base^2=169-25

Base^2=144

Taking sq root on both sides

Base=12

Now

Cosine C=base/hypotenuse

Cosine C=12/13

step-by-step explanation:

. your answer will contain x - and y -terms. (1 point) x ( ¿¿ 2 − 7 ) 2 +( y 2 − 9 ) 2 √ ¿ 12. what is the distance from the directrix (the crocodile river) to the point ( x , y )? write this equation. your answer will contain a y -term.

correct answer is c. just did it
