Answer:
x = 9
Step-by-step explanation:
→Looking at the angles, you can see that a right angle is formed. This means that there must be another right angle (90 degrees) formed with the numbers. You can set up the equation, like so:
3x + 6 + 57 = 90
→Add like terms (6 and 57):
3x + 63 = 90
→Subtract 63 from both sides:
3x = 27
→Divide both sides by 3:
x = 9
