Question

The value of X is 36 degrees less than the value of y. Find the values of X and Y!!

Answer 1

x=72, y=108

Explanation:

y-36=x

`\left \{ {{y-x=36} \atop {y+x=180}} \right.`

⇒ 2y=216

y=108

108-36=x

x=72

Answer 2

• x+y=180--(1)
• x=y-36=>x-y=-36-(2)

Adding both

• 2x=144=>x=72

Put in eq(1)

• y=180-72=108°
