change the y with the x and solve for y making it the last one
9514 1404 393
(b) 60°
The sum of angles in a pentagon is 540°, so you have ...
90° +90° +150° +x +150° = 540°
x = 540° -480°
x = 60°
option c
x + 4 = 64
and
option e
x = 60
Given in the question an expression
3∛x+4 = 12
∛x + 4 = 12/3
∛x + 4 = 4
Take cube on both sides of the equation
∛(x + 4)³ = 4³
x = 64 - 4
