Answer:
- see below for a sketch
- 12 km
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.

Answer;
Answer:
25/28
Step-by-step explanation:
5/4 x 5/7 = 25/28
To take a root of a fraction, take the root of the numerator and denominator separately
Write the number in exponential form with a base of 2 to the second power
Write the number in exponential form with a base of 3 to the third power
Reduce the index of the radical and exponent with2
Reduce the index of the radical and exponent with 2
Then it’s gonna be 2/3 2over3
-3 2/3
Reduce the numbers with greatest common divisor 3
Then the answer will be -2
