Question

Triangle LMN is similar to triangle PQR. The length of PQ is twice the length of LM.

If the cosine of angle L is 9/19 , what is the cosine of angle P?
A. 18/19


B. 19/9


C.9/19


D. 28/19

Answer 1

The correct answer is letter c

Answer 2

C.
`(9)/(19)`

Explanation:

Since triangle LMN is similar to triangle PQR angle P and angle L are congruent.

If
`\cos(L)=(9)/(19)`,then
`\cos(P)=(9)/(19)`

The correct option is C.
