x = 83°

y = 83°

Step-by-step explanation:

Angles in a triangle add up to 180°, so:

Equation: 31 + 66 + x = 180

Combine like terms: 97 + x = 180

Subtract 97 from both sides: x = 83°

They are vertical angles (x = y), y will also be 83°!

Step-by-step explanation:

x+31°+66°=180°

x=180°-31°-66°

x=83°

and x°=y° due to both are vertically opposite angle.

y°=83°.

hope this helps you.

452,489 to the nearest thousand is 452,000

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*
