Answer:
Step-by-step explanation:
The overall angle in total is 90 degrees. The angles 'x+42' and '3x' equal ninety degrees, so we get the equation:
x + 42 + 3x = 90
4x + 42 = 90
4x = 48
x = 12
Hope that helps!
Answer:
x=12
Step-by-step explanation:
Since it is on a right angle we can equate the sum of these 2 angles to 90:
3x+x+42=90
Simplify:
4x+42=90
Subtract 42 from both sides:
4x+42-42=90-42
Simplify:
4x=48
Divide both sides by 4
4x÷4=48÷4
Simplify
x=12
