Question

find the hots question of triangle​

Answer 1

Step-by-step explanation:

1. ∠A + ∠B + ∠C = 180⁰(sum of angles of triangle is 180⁰).

∠D + ∠E + ∠F = 180⁰(sum of angles of triangle is 180⁰).

Sum of angles A,B,C,D,E and F = 180⁰+180⁰ = 360⁰

2. y = 180⁰-(45⁰+90⁰) = 180⁰ - 135⁰ = 45⁰

x= 180⁰- ( 40⁰+90⁰) = 180⁰-130⁰ = 50⁰

Hope it helps you...
