Step-by-step explanation:
This time round, use SOH method (Sin angle = Opposite/Hypotenuse)
given Opposite = 7
Hypotenuse = 10

Answer: 1668.2
Multiply 1668.2×45 and get 75,069
Answer:
Part A = 10in = 35 ft
= 20 = 70 ft
Part B =
$ 178.5
Step-by-step explanation:
The coordinates of the other endpoint are (-8, 18)
The measure of the interior angles would be 120°, and they would all add up to be 720°
