Answer:

x = 28

Step-by-step explanation:

The 2 angles must add up to 180°, as definition of a line.

4x + 7 + 2x + 5 = 180

6x + 12 = 180

6x = 168

x = 28

X^3 = 125 over 27 CAN I PLEASE GET HELP
Zinaida [17]
X³ = 125/27

Cube root both sides to isolate the variable:

∛x³ = ∛(125/27)

x = ∛(125/27)

∛125 = 5, ∛27 = 3

x = 5/3
