Answer:
2x+30
Step-by-step explanation:
The formula for perimeter is
P = 2(l+w)
= 2(2/3 x+10 + 1/3 x+5)
= 2(2/3 x + 1/3 x+10+5)
= 2 (x+15)
Distribute
2x+30

Answer:
QR ≈ 16.2 ft
Step-by-step explanation:
Using the tangent ratio in the right triangle.
tan62° =
=
=
( multiply both sides by 8.6 )
8.6 × tan62° = QR , then
QR ≈ 16.2 ft ( to the nearest tenth )
