Answer:
y = 115
Step-by-step explanation:
5 angles should total to 540°.
135+112+88+90+y= 540
425+y=540
y = 115
Answer:
Let x = the number
A negative number is 42 less than its square ⇒
x = x2 - 42
x2 - x - 42 = 0
(x - 7)(x + 6) = 0

But since it is given that x is negative, the final answer is x = -6.
