Two forces of 7 lb. and 14 lb. act on a body at right angles to each other. find the angle their resultant force makes with the force of 14 lb. a. 18 b. 27 c.63

The angle between resultant force and force of 14lb is 26.60≈ 27°

Answer B.

Step-by-step explanation:

Two given forces and resultant force form right triangle. The resultant force is hypotenuse, two given forces are right sides of the right triangle.

We can get required angle in accordance with tangens theorem

tanα= 7/14= 0.5 => α= 26.6 ≈ 27°

Good luck!!!

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.
