solve for x:

10°
18°
20°
22.5°

x=10

Step-by-step explanation:

Because the image shows a right angle, we know it's 90 degrees. the two angle measures added together to create the 90 degrees are represented by 4x and 5x, so;

4x+5x=90 (combine like terms)

9x=90 (divide each side by 9 to isolate the variable)

x=10

just put them in order

step-by-step explanation:

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
