Find the area of the shaded triangle

Area of a triangle is 1/2 x base x height.

The base of the shaded triangle is 2 ft. the height is 4 ft.

Area = 1/2 x 2 x 4 = 4 square feet.

4 ft²

Step-by-step explanation:

A = 1/2bh           Use this equation to find the area of the triangle

A = 1/2(4)(4)       Multiply

A = 1/2(16)          Multiply

A = 8                  Area of entire triangle

A = 1/2(2)(4)      Multiply

A = 1/2(8)          Multiply

A = 4                 Area of triangle not shaded

Take the area of the whole triangle minus the area of the unshaded part

8 - 4 = 4 ft²

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
