How do I start the equation?

Step-by-step explanation:

Well they add up to a straight line which would be 180 degrees. That means 40, 6x+2 and 90 all add up to 180

40 + 90 + 6x + 2 = 180

x = 8

Step-by-step explanation:

40 + 6x + 2 = 90° because these angles are complementary

6x = 90 - 42

6x = 48 divide both sides by 6

x = 8

welll its a very hard question but ill

step-by-step explanation:

first you take the 6 dollars and add 10 to it then add the 50 to that then multiply by 8 with xy and your answer will be
