Answer:
16.8°
Step-by-step explanation:
The Law of Cosines can be rearranged to give the angle measure.
angle Q = arccos((p² +r² -q²)/(2pr))
angle Q = arccos((690² +450² -290²)/(2×690×450))
angle Q = arccos(594500/621000) ≈ 16.7985°
The measure of angle Q is about 16.8°.
Answer:
4x-10
Step-by-step explanation:
Multiply both by 2, 2x times 2 is 4x, and 5 times 2 is 10, so it becomes 4x-10.
