Answer:
about 1099 pounds
Step-by-step explanation:
The weight of the truck is directed downward. It is countered by a force normal to the plane of the hill and one that is parallel to the plane of the hill. The question is asking about this latter force.
The magnitude of the force parallel to the hillside required to keep the truck stationary is ...
(2600 lb)·sin(25°) ≈ 1098.81 lb ≈ 1099 lb
2 is the smallest number out of the 5
Rewriting 278-159=119, we get 159 + 119 = 278. The first term is 159. If we add 119 once, we get 278; if we add 119 again, we get 397; and so on. This is an arithmetic sequence.
One triangle has 180°
33°+57°=90°
180°-90°=90
So Z is 90°
so it's a right triangle.
