In order for the parallelogram to be a rhombus x = ?
Zina [86]

Answer: x= 207.8873386

Step-by-step explanation:

expecting both 2x-15 and 3x are angles in radiant, let's draw a rhombus ABCD

∠ABC = 2x-15

∠ BCD = 3x

∠ABC + < BCD= π ( 180° in radiant)

2x - 15 + 3x = π

5x - 15 = π

x - 3 = 1/5π

= 3.628318531 = 207.8873386

2x−15°+3x=180

5x-15°=180

5x=195°

x=39°
