We can see that

this is at right angled

because these two lines are perpendicular

so, it's angle will be 90 degree

and sum of these two angles must be 90 degree

so, we get

[tex] x+3x+10=90 [/tex]

now, we can solve for x

[tex] 4x=80 [/tex]

we get

[tex] x=20 [/tex]..............Answer

The angles form a right angle, so make an equation where they add up to 90 degrees.

x + (3x + 10) = 90

Combine like terms.

4x + 10 = 90

Subtract 10 from both sides.

4x = 80

Divide both sides by 4.

x = 20
