Question

What is the value of x?
D x= 2.25
DX = 11.25
0 x = 13
0 x = 22

Answer 1

`x=22`

Explanation:

see the attached figure to better understand the problem

we know that

The exterior angle is the sum of the 2 opposite interior angles of a triangle

so

In this problem

`(6x+1)^o=79^o+(2x+10)^o`

solve for x

Combine like terms

`6x+1=89+2x`

Group terms

`6x-2x=89-1`

`4x=88`

divide by 4 both sides

`x=22`
