Question

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

Answer 1

Answer:

$x=22$

Step-by-step 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

$x=22$
