Isosceles trapezoid
<ONM = <LON = 100
<OLM = <NML = 1/2(360 - 2(100))
= 1/2(360 - 200)
= 1/2(160)
= 80
Answer
<OLM = 80 degress
Since the ground floor has 52 windows, and every floor, here are 6 fewer windows than the floor below it, we make a expression.
52-y=x.
We are trying to solve for x, not y.
In order to get 'y,' you have to multiply 8 by 6. Which is going to be 48.
(If you don't know multiplication, respectively.)
So now that we solved for y, =48 .... 52-48= ....... = x
Now all we have to do is simply subtract.
x=4.
So the answer to the problem is 4 windows on the 8th floor.
The answer is 15/5 which is 3
Correct answer is: 3
well if he answers half a question per minute then it would take 2 minutes to answer a question. Therefore if you flip the numerator and the denominator you can multiply that by how many questions are being asked as shown:
q=6
1/2x2=1
2/1=2xq
2x6=12
?=12 minutes
