Question

Find the value of x, y, and z in the rhombus below.

Answer 1

Consecutive angles in a paralleogram have sum 180

$\\ \rm\rightarrowtail 5z+4+86=180$

$\\ \rm\rightarrowtail 5z+90=180$

$\\ \rm\rightarrowtail 5z=90$

$\\ \rm\rightarrowtail z=18$

And

• 7y+3+86=180
• 7y+89=180
• 7y=91
• y=13

And

opposite angles are equal

• 6x+8=86
• 6x=78
• x=13
