Question

for what value of x is the parallelogram a rectangle?

the parallelogram is a rectangle when x = \square.
(type a whole number.)
(3x - 4)°
(2x + 13)°

Explanation:

Step1: Recall rectangle property

Diagonals of a rectangle are equal, so their opposite angles are equal.

Step2: Set angles equal

$3x - 4 = 2x + 13$

Step3: Solve for x

Subtract $2x$: $x - 4 = 13$; add 4: $x = 17$

Answer:

17
