Answer:
ans: ( x + 1 )= 44⁰ 30"
( x + 2 ) = 45⁰ 30"
Step-by-step explanation:
sum of all angles of triangle = 180⁰
=> (x + 1 ) + ( x + 2 ) + 90⁰ = 180⁰
=> 2x + 3⁰ + 90⁰ = 180⁰
=> 2x + 93⁰ = 180⁰
=> 2x = 180⁰ - 93⁰
=> 2x = 87⁰
=> x = 87/2
=> x = 43⁰30"
side1 = 43⁰ 30" + 2 = 45⁰ 30"
side 2 = 43⁰ 30" + 1 =44⁰ 30"
verification:
45⁰30" + 34⁰ 30" + 90⁰ = 180⁰
90⁰ + 90⁰ = 180⁰
180⁰ = 180⁰
