I NEED HELP PLEASE, THANK YOU. :)

Solve for x in the figure below.

We can see that there is a right angle in the figure and that both the 50° and (3x + 4)° angle make a complementary angle (90°).

We can write an equation:

90 = 50 + 3x + 4

Solve for x.

90 = 50 + 3x + 4

~Combine like terms

90 = 54 + 3x

~Subtract 54 to both sides

90 - 54 = 54 - 54 + 3x

~Simplify

36 = 3x

~Divide 3 to both sides

36/3 = 3x/3

~Simplify

12 = x

Therefore, x = 12

Best of Luck!

step-by-step explanation:

no

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )
