Answer:
(20, 14) If the first y is positive
(5/2, -7/2) If the first y is negative
Well, we can input both variables to check and see if the numbers hold.
-691 = -51(-15) - 74
-691 = 765-64
-691 = 701
(-15, -691) does not make the equation true.
Use trigonometry:-
sin 26.5 = y / 15 (as sin = adj / hyp)
y = 15 sin 26.5 = 6.69 feet to nearest hundredth
27 divided by 100 is 0.27 so 0.27 is one percent now 17 divided by 0.27 is about 62.963 so 17 is 62.963% of 27 hope this helped.
