Distribute the -6.2 to -3 and -7.
-6.2×-3=18.6 -6.2×-7=43.4
14+18.6+43.4=76.
Answer:
-6 + 57
Step-by-step explanation:
Substitute the value of the variable into the equation and simplify.
Answer:
Step-by-step explanation:
x and y = 27° : they are alternate angle to angle FDE = 27°
Answer:
d - 20.4 cm
Step-by-step explanation:
The perimeter by definition is the sum of all the sides of a figure. We have 3 of the 4 sides and we know the sum of them is 77:
14.4 + 19.5 + 22.7 + d = 77 and
56.6 + d = 77 so
d = 20.4
Answer:
15
Step-by-step explanation:
Angle 2 is 2x+10
angle 4 is 4x+80
and from the figure we can understand that when we add these 2 equations
We get
6x+ 90= 180
6x = 180 - 90= 90
6x= 90
x = 90 ÷ 6 = 15
answer = 15
