Question

Find the unknown angle.
step by step.
​

Answer 1

Answer:

x = 35⁰  and y = 90⁰

Step-by-step explanation:

AB ∥ CE and BC is a transversal        (Given)

=> ∠ABC + ∠BCE = 180⁰      

=> 55⁰ + (x+90)⁰ = 180⁰

=> x = (180 - 145)⁰

=> x = 35⁰

∠A + ∠B + ∠C = 180⁰

=> y + 55⁰ + 35⁰ = 180⁰

=> y = 180 - 90 = 90⁰
