Question

Given that ABCD is a rhombus, what is the value of x?

Answer 1

A. 28
B. 56
C. 48.5
D. 18
E. 36
F. Cannot be determined

Answer 2

would this be done the same way as the other one @Hope_nicole

Answer 3

in any rhombus, the diagonals bisect the interior angles

so we can say

Answer 4

any rhombus is a parallelogram, so the adjacent angles are supplementary, which means

(5x-18)+(5x-18) + (x)+(x) = 180

10x - 36 + 2x = 180
