Solve for x plz. a

Okay!

All we need to do to solve for x is to set up an equation!

the equation 3x + 4 represent the number of degrees of the bottom angle

→To set up the equation, however, we must find what the bottom angle is!

→This is easy since we know that all triangle are 180°

→The diagram already gives us to angles, so to find the third angle, we use simple subtraction

*the little corner with the red square is always 90°

180 = 90 + 50 + ?

? = 180 - 90 - 50

? = 40°

The angle is 40° !

→Now we can finally find x!

→To find x, we just set the equation they give us equal the degrees of the angle that we just found

3x + 4 = 40°

SOLVE !

3x = 36

x = 36/3

x = 12

We did it! Hope I helped ! :)
