Answer:
30 degrees
Step-by-step explanation:
A right angle is 90 degrees. Subtract 30 and you get 60. Then divide it by two because the leftover is 2x.
Answer:

Step-by-step explanation:
Well we can simplify the numerator, by multiplying the 4 by the 6 and the m^3 and m^4 (add the exponents, explained in one of my previous answers I think)
This gives us the fraction: 
We can now divide the m^7 by m^2 by subtracting the exponents, and the reason why this works, is you're simply cancelling out the m's, If we express this in expanded form we have the following fraction: 
Since there is two m's in the denominator and there is also two (more than two) m's in the numerator, we can cancel those two m's out, and we get the fraction:
which can be simplified in exponent form as:
, now all we have to do is divide the 24 by the 3, to get 8
This gives us the answer: 
The shape shown is a cone and the cones perpendicular cross section is a triangle.
If you need the parallel cross section then it will be a circle.
The answer is A.
Hope this helps :)
so the first year is $1700
in that case: a(1)=1700
each year it goes up by $70
then in nth year it's: a(n)=a(n-1)+70
