Question

Finddddd the value of x

Answer 1

Explanation:

Answer 2

1)x = 30°

2) x = 46°

3) x = 20°

4)x = 53°

Explanation:

Angle sum property of triangle:

The sum of all three angles of a triangle is 180°.

1) x + 60 + 90 = 180

x + 150 = 180

x = 180 - 150

`\sf \boxed{\bf x = 30^\circ}`

2) 57 + 77 + x = 180

134 + x = 180

x = 180 - 134

`\sf \boxed{\bf x = 46^\circ }`

3) 134 + 26 + x = 180

160 + x = 180

x = 180 - 160

`\sf \boxed{\bf x = 20^\circ}`

4) 65 + 62 + x = 180

127 + x = 180

x = 180 - 127

`\sf \boxed{x = 53^\circ}`
