Answer:
x = 30
m<Y = 60
m<Z = 60
m<X = 60
Step-by-step explanation:
All of this should add up to 180 so...
2x + 2x + 3x - 30 = 180 (collect like terms)
7x - 30 = 180 (add 30 on both sides)
7x = 210 (divide by 7 on both sides)
x = 30
PLUG IN
2(30) = 60
3(30) - 30
90 - 30 = 60
m<Y = 60
m<Z = 60
m<X = 60
equilateral triangle

Answer:
x = y/2w - 1/2
Step-by-step explanation:
The correct answer is that the length of one edge must be 1 unit. One cubic unit has a length, width, and height of 1 unit. V = 1 x 1 x 1.
We know that
<span>124 7/8 gallons of water drained from a pool in 25 minutes
124 7/8 gallons------> (124*8+7)/8-----> 999/8 gallons----> 124.875 gallons
by proportion
124.875 gallons/25 minutes=x gallons/1 minute
x=124.875/25-----> x=4.995 gallons/minute
round to the nearest gallon------> 5 gallons/minute
the answer is
5 gallons/minute

You use Pythagorean theorem...a^2+b^2=c^2
a=12ft
b=47-31.. height of the triangle
c=distance between two roof tops
(12)^2+(16)^2=c^2
144+256=c^2
400=c^2, take square root of both sides
c=20ft
