What is the value of y?

enter your answer, as an exact value, in the box.

y =

Value of y=8.66

Step-by-step explanation:

We are given the length of base of right angled triangle and one angle.

We have to find the length of the perpendicular.

We will find this by using the formula:

√3=y/5

y=5√3

y=8.66

Hence, value of y=8.66

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: 12

step-by-step explanation:

because yes
