Question

Find the value of x​

Answer 1

Answer:-

x = 60°

Explanation:-

Sum of angles of triangle = 180°

Other 2 Angles = 30° , 90°

So, x + 30° + 90° = 180°

x + 120° = 180°

x = 180° - 120°

x = 60°

Answer 2

ACCORDING TO FIGURE 2 SIDES ARE GIVE AND 1 SIDE WE HAVE TO FIND

GIVEN SIDES-;30⁰ and 90⁰ and x

According to supplementary rule we will

30⁰+90⁰+x=180⁰

120⁰+x=180⁰

x=180⁰-120⁰

x=60⁰
