Answer:
Step-by-step explanation:
These problems are based on triangle ratios. You cannot use the Pythagorean theorem to solve them.
The first triangle is a 45 45 90 degree triangle (I'm talking about the angles), and so, the ratio is 1:1:
, so I have to divide the hypotenuse by to get the legs. The hypotenuse is 15
, so that divided by is 15
. X is the same length as y because of the triangle ratio, so both x and y for the first triangle are 15.
The second triangle is a 30 60 90 degree triangle, so the ratio is x:x
:2x. The short leg is 7, so 7 * 2 is the hypotenuse, which is 14. The long leg is 7 * , which is 21. So, x for the second triangle is 14, and y for the second triangle is 21.

Step-by-step explanation:
Answer:
520 - 303.93 - (10.99 * 4) - 25.25 - 73.43x ≥ 0
-
1) Parentheses
520 - 303.93 - 43.96 - 25.25 - 73.43x ≥ 0
-
2) Combine like terms
146.86 - 73.43x ≥ 0
-
3) Get the variable term alone
-73.43x ≥ -146.86
-
4) Divide to solve
x ≤ 2
** dividing by a negative number, the inequality sign flips **
ANSWER :
x ≤ 2
