Answer:
y = 3
Step-by-step explanation:
Pythag theorem : ( only applies to RIGHT triangles)
Hypotenuse ^2 = leg1 ^2 + leg 2^2
(7y-1)^2 = (5y-3)^2 + (5y+1)^2
49 y^2 - 14y +1 = 25y^2 -30 y + 9 + 25y^2 + 10y + 1
-y^2 + 6y -9 = 0
or y^2 -6y + 9 = 0 solve by factoring or using Quadratic Formula
( y -3)(y-3) = 0 shows y = 3
324???? 36x9 sorry if im not right
First find the vertical distance from Charlie to the plane by subtracting the altitude of Charlie's eyes from the altitude of the plane: 1700-5.2=1694.8 ft. Let d be the distance from Charlie to the plane. Use the trignometric relationship in the right triangle: sin32=1694.8/d. d=3198 ft.
Answer:
d
Step-by-step explanation:
An angle is straight if and only if its measure is 180
