Answer:
157
Step-by-step explanation:
Simplify the following:
125 - (5 - 9)^3/2
5 - 9 = -4:
125 - (-4)^3/2
(-4)^3 = (-1)^3×4^3 = -4^3:
125 - (-4^3)/2
4^3 = 4×4^2:
125 - (-4×4^2)/2
4^2 = 16:
125 - (-4×16)/2
4×16 = 64:
125 - (-64)/2

Step-by-step explanation:
Answer:
x = 35
y = 100
Step-by-step explanation:
∠AEB and ∠DEC are vertical angles because they are opposite each other; they are also equal because of this. We can write an equation to model the situation:
∠AEB = ∠DEC
50° = x° + 15°
x = 35
∠AEB and ∠AED are supplementary because the form a line; this means they add up to 180°
∠AEB + ∠AED = 180°
50° + y + 30° = 180°
y + 80° = 180°
y = 100
