The complement of an angle is 90 minus the angle, or
90 - x = complement angle
if x is 18 more than 3 times it's complement, then
x = 3(complement angle) + 18
We can substitute "90 - x" for the "complement angle" in the second equation:
x = 3(90 - x) + 18
distribute the 3 to the 90 and the x
x = 270 - 3x + 18
add 3x to both sides
4x = 270 - 18
4x = 252
x = 63
the measure of angle x is 63 degrees
Answer:

Step-by-step explanation:
Area = <span>π*r^2
= </span><span>π * 9^2
=81</span><span>π square feet. - B is your answer</span>
A+S=589
S=a-61
A+A-61=589
2a=589+61
2a=650
A=325
S=325-61
S=264
Hope this helps
Answer:
if you can split it in half its: $38.75
if you cant its: $46.50
Step-by-step explanation:
half:
1. 8+8+4=20
2. 15.50 divided by 2 = 7.75
3. 7.75 + 15.50 + 15.50 = 38.75
not half:
1. 8+8+8= 24
2. 15.50 times 3 = 46.50
