Question

What are the values of​ x, y, and​ z?

Answer 1

To find value of x

Formula applied:

Exterior angle=Sum of interior angles

Answer:

• x=66⁰+45⁰

• x=111⁰✔

To find value of z:

Formula applied:

Exterior angle=Sum of interior angles

Answer:

• 119⁰=43⁰+z⁰

• 119⁰-43⁰=z⁰

• z⁰=76⁰✔

To find value of y:

• ∠1+66⁰=180⁰(L.P)

• ∠1=180⁰-66⁰

• ∠1=114⁰

Formula used:

Sum of angles of a triangle =180⁰

Answer:

• ∠ 1+30⁰+y⁰=180⁰

• 114⁰+30⁰+y⁰=180⁰

• y⁰=180⁰-144⁰

• y⁰=36⁰✔
