Find the value of x please

Step-by-step explanation:

In isoceles triangle two sides are equal and two angles are equal.

Then,

∠R = ∠T = (5x-40)°

Then,

∠RTS + ∠STU = 180° (bcoz it lies on a straight line)

(5x-40) ° + 5x = 180°

10x = 220°

x = 22°

Therefore,

Option A is correct✔

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 : )
