Answer:
x=22.5°
Step-by-step explanation:
∵it's a rhombus
∴each 2 opposite sides are parallel
∴the angel adjecent angle the angle 3x is equal to the angle 6x
∴ 3x+6x=180
8x=180
⇒x=22.5
First you have to find the like terms
3xy + 10xy - 2xy and -5x + 2x
After that you solve for the like terms to find the final answer
11xy-3x
