Answer:
C. x = 18, y = 9
Step-by-step explanation:
In a 30-60-90 triangle,
longer leg =
(shorter leg)
hypontenuse = 2(shorter leg)
In your case, the shorter leg = 9
therefore, y = 9
and x = 2(9) = 18
Answer:
b. x+y=18
20x+25y=400
Step-by-step explanation:
3 1/7 because it is a mixed fraction
24 ten thousands means 24 x 10, 000 which is equivalent to 240, 000. see attached file for the illustration.
