Answer:
Step-by-step explanation:
The distance can be calculated using the Law of Cosines. The angle internal to the triangle at Q is (180°-(146° -65°)) = 99°. Then the distance PR can be found from ...
PR² = PQ² +QR² -2·PQ·QR·cos(∠PQR)
PR² = 6² +10² -2·6·10·cos(99°) ≈ 154.77
PR ≈ √154.77 ≈ 12.44 . . . . km
The distance PR is about 12 km.
y=3
it is because X=-2 had crossed the point y=3
hope this help you!!!! ;))))))
-2×-y=3-9×-y=17
=2×+9×=1y+1y=17+3
11×=2y=20
11=y=20÷2
11y=10
y=10/11
4y²-1/4 is the required answer
Answer: The correct answer is (B)
