Answer:
PQ = 16
Step-by-step explanation:
Using the cosine ratio in the right triangle and the exact value
cos60° =
, then
cos60° =
=
=
=
( cross- multiply )
PQ = 8 × 2 = 16
4n - 7 = 13
4n = 20
n = 5. Hope it helps!
Answer: Start off and multiply 12x30=360
Step-by-step explanation: He will recieve 360$
Sin(θ - 180)
sin(θ)cos(180) - cos(θ)sin(180)
sin(θ)[-1] - cos(θ)[0]
-sin(θ) - 0
-sin(θ)
