Question

in the given diagrams find the value of x in each case​

Answer 1

Answer:

we know that the sum of all angles of triangle is 180°

so x+90+30 = 180°

x=60°

Answer 2

Here,

angle 1 - 30°

angle 2 - 90°

angle 3 - x

According to que. {By angle sum property}

angle 1 + angle 2+ angle 3- 180°

30° + 90° + x - 180°

120° + x- 180°

x - 180° - 120°

x - 60°
