Answer:
Step-by-step explanation:
Since you know the angle is a right angle, you can say that the two equations equal 90. A right angle is 90 degrees
3x+40+4x-6=90
Then Simplify
7x+34=90
Then Subtract:
7x=56
Then Divide:
x= 8
After, plug x into the angle equations
1. 3(8)+40= 64
2.4(8)-6= 26
The angles are 64 and 26
