Answer:
a) a + c = 90
d) a + b + c + 30 = 180
e) The angles marked a and b are vertical
f) The angles marked a and c are complementary.
Step-by-step explanation:
A complementary angle is and angle that has a sum of 90 degrees. A vertical angle is 2 angles facing each other, that are completely identical. 180 degrees is the sum of a strait line. 90 degrees is a right angle.
Hope this helps! Have a wonderful rest of your day!

Given:
Lateral Area = π * r * (√h² + r²)
Lateral Area = 100 in² ; height = 5 in
I find it hard to derive the formula of r because of the radical sign. So, I'll just plug each radius to the formula to check confirm the given lateral area.
a) r = 1.52138 ⇒ LA = 24.98
b) r = 4.658 ⇒ LA = 100
c) r = 78 ⇒ LA = 19152.68
d) r = 6.7432 ⇒ LA = 177.84
The radius is B.) r = 4.658 inches
Answer:



And finally we can convert this into money like this:

So they spent every day approximately in total $ 4815291.6 dollars
Step-by-step explanation:
For this case we can convert the average power into Kw like this:

Now on average we know that one person use on average this power over 6.3 hours per day so then we have the following consumption rate:

And now we know the total population so then the total consumption per day would be:

And finally we can convert this into money like this:

So they spent every day approximately in total $ 4815291.6 dollars
Hi can we see the choicest
