Find the missing side lengths the triangle is 30-60-90

y= 4

x=8

Step-by-step explanation:

30-60-90 rule. the side opposite of 30 degrees is y, the side opposite of 90 degrees is 2y, and the side opposite of 60 degrees is y  . since 4 is next to the square root that makes it y. y = 4 and 2y= 8.

.

step-by-step explanation:

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
