Answer:
B. 16/25 x is the answer
Step-by-step explanation:
lets find the proportional relationship,
y = kx
2/5 = k * 5/8
k = (2/5) / (5/8)
k = 16/25
so if k, constant is 16/25
<u>equation is:</u>
<em>y = 16/25 x</em>

Answer: 57°
Given : In triangle PQR, the side PQ is 17, QR is 15, and PR is 14.
We use law of cosine formula


225 = 196 + 289 - 476 cos(P)
225 = 485 - 476 cos (P)
Subtract 485 on both sides
-260 = -476 cos(P)
= cos(P)
P = 
P= 56.89202
So measure of angle P is 57 degrees
