Look at the figure below:

if sin y° = 7/q and tan y° = 7/r ,what is the value of cos y°?
cos y°= r/q
cos y° = 7r
cos y° = 7q
cos y°= q/r

2: 10

step-by-step explanation:

the answer to this is a. a^2 + b^2 = c^2

step-by-step explanation:

assume that y=mx+n

you may see as , where

in we change places of numerator and denominator, then we insert an opposite sign

and substitute m=-1/3 in the equation y=mx+n

point (4,2), so we substitute x=4, y=2 to the equation and calculate

the answer is
