Answer:
correct
Step-by-step explanation:
if you are dividing between two numbers and one of them is negative, then the answer is negative. If there are two negatives being divided, on the other hand, they will cancel out and the quotient will be positive. It's the same way for multiplication
Answer:
Opposite sides of the parallelogram are equal. Here, 60°+60°+ Angle ZWX + Angle ZYX = 360°
or,2* Angle ZYX = 240° [ Angle ZWX = Angle ZYX]
So, Angle ZYX = 120°
Then, In ∆ENY;
102° + (120-84)° + Angle ENY = 180° [Sum of all angles of a triangle.]
or, 36° + Angle ENY = 78°
So, Angle ENY = 42°
Answer:
20 1/4 ft
Step-by-step explanation:
Subtracting the four given lengths from 75 feet will tell you how much is left.
75 - (12 1/3 +16 1/6 +11 3/4 +14 1/2) = 75 -54 3/4 = 20 1/4
Gabriel has 20 1/4 ft of material left for his 5th banner.
