Question

Find the area of the parallelogram. Round to the
nearest tenth.

Answer 1

Explanation:

Note all arguments of trigonometric functions are in degrees.

Since tan(35)=4/(longer dotted leg of the triangle), the length of this longer dotted leg is thus 4/tan(35).

Since A=bh, the area is (4/tan35)(12), and you can just plug this into a calculator.
