Answer:
Step-by-step explanation:
We know the perimeter of a triangle is the sum of all the sides( two legs and one hypotenuse).
By pythagoras we know that
and the perimeter is 
.
Since P=24 and a=6 we have these equations:
From the last equation we have 
. Replace h in the first equation we get that
and h=18-8=10
Answer:
4b-3d
Step-by-step explanation:
first add the like terms
2b - 8b + 10b = 4b
12d - 15d = -3d
then add the results.
Answer:
180 sq. in.
Step-by-step explanation:
The formula for the volume of a circular cone is V = (πr^2h)/3
So, 900 = (15πr^2)/3
2700 = 15πr^2
180 = πr^2 = area of the circular base
Answer:
a = 127°
Step-by-step explanation:
The 3 angles lie on a straight line and have a sum of 180°, that is
15° + a + 38° = 180°
53° + a = 180° ( subtract 53° from both sides )
a = 127°
No it is not a order pair. It’s not one because I did the work.
