Answer:
X = 13 ⁰
Y = 38⁰
Step-by-step explanation:
Mark the corner of the triangle as A , B , C
Interior angle A = 180⁰ - 96⁰
= 84⁰
Interior angle B = 4x+6 = Exterior angle B ( vertically opposite angles)
Interior angle C = 180⁰-9x -25⁰
= -9x + 155
By the sum property:
<A + <B + <C = 180⁰
84+ 4x+6 -9x+155 = 180⁰
-5x + 245 = 180⁰
- 5x = - 65⁰
x. = 13
Angle A = 84⁰
Angle B = 4x+6 = 4×13+6 = 58⁰
Angle C = -9x+155 = -9×13+155 = 38⁰
Value of y will be equal to interior angle C
i.e 38⁰ ( vertically opposite angles)
