Answer:
EF=22
C=70°
B=110°
Step-by-step explanation:
Trapezoids have to have a total of 360° and there are complementary angles.
You want to find the area of the circle. The formula for the area of a circle is A=πr^2 (Area=pi times radius squared). The diameter is the distance across the circle. Radius is half the diameter. Diameter=3. 3 divided by 2 equals 1.5. So, plug it into the equation. A=π1.5^2 (Area=pi times 1.5 squared).
2x+10x combine like terms
12x
2(x-4)+4 Distribute 2
2x-8+4
combine like terms
2x-4
Battery is down currently = 2/5
Battery drains at the rate of 1/9 every hour.
Remaining battery life of Vera = 1 -2/5 = 3/5
Let y we the number of hours battery will last.
So, 1/9 y = 3/5
y = 27/5
y = 5 + 2/5 hours
y = 5 hrs and 24 mins
So battery will last another 5 hrs and 24 mins.
hope this helps:)
