Solve for x please

x=22,5°

Step-by-step explanation:

x+3x=4x

4x=90

x=90/4

x=22,5

x =  22.5

Step-by-step explanation:

Hi there bud,

We have a straight line at the bottom which is cut by perpendicular line going up. As we can see the angle of the left hand side equals 90 degree, and when we have a straight line we get a linear pair which means 180 degree.

So now we already know that one angle of the 180 degree's is 90, let find the other which we do by subtracting 90 from 180 for which we get 90 degrees.

Now that we have got 90 degree on the right hand side let's solve for x.

3x + x = 90

4x = 90

x= 90/4

x =  22.5
