The figure below shows a right triangle:
a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.
what is p ÷ r equal to?
tan x°
tan y°
sin y°
cos x°

(a)tanx

step-by-step explanation:

it is given that there is a right triangle with hypotenuse equal to q units and the length of the legs equal to p units and r units.  

we know that , and then, from the given figure, we have

p is the perpendicular and r is the base of the given triangle, then

thus, option a is correct.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

answer: 5100 just subtract
