Answer:
Explanation:
m∠EBC = 45°
3x + 9y = 45
Divide the entire equation by 3
x + 3y = 15 --------------------(I)
m∠EAB = 45
5x + 5y = 45
Divide the entire equation by 5
x +y = 9 -------------(II)
Multiply equation (II) by (-1)
(I) x + 3y = 15
(II)*(-1) - x - y = -9 {Now add}
2y = 6
y = 6/2
y = 3
Plugin y = 3 in equation (I)
x + 3*3 = 15
x + 9 = 15
x = 15 - 9
x = 6
