Every interior angle of square is a right angle (90°)
<span>
5x - 10 = 90
5x = 90 + 10
5x = 100
x = 100/5
x = 20</span>
Answer:
27
Step-by-step explanation:
The central angle of 120° is 1/3 of the entire circle of 360°, so the sector area is 1/3 of the circle area:
1/3×81 = 27
The sector area is 27.
Short leg = 18 Long leg= 24 Hypotenuse= 30
My calculations were simple trial and error. I started with a trial of 10 for the short leg to begin with, averaging and estimating the appropriate proportions based off 6 additional increments. Sorry I don't have an algebraic method for you. Hope this has helped somewhat :)
Answer:
Step-by-step explanation:
Recall the formula:
We apply this formula to simplify 
This implies that:
This simplifies to
