Find Cos(a) in the triangle Choose 1 Answer

A. 24\25

B.7/24

C.24/7

D.7/25

A

Step-by-step explanation:

The definiton of cosine is the adjacent over hypotenuse. Here, the adjacent to a is 24, and the hypotenuse is 25. So, cos(a) = 24/25

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
