Find the value of X in the isosceles triangle shown below.
BigorU [14]

Answer:

D) Square root of 48

Step-by-step explanation:

We have to split the triangle in half and then multiply that by two for the answer. Then we use a²+b²=c² because the two triangles are right triangles, and we know b=4 and c=8, so a²+(4²)=8², or a²+16=64

a² would have to equal 48. a=√48.

aev [14]
The total volume of the three cylinders is given by:
 V = (3) * (pi) * (r ^ 2) * (d)
 Where,
 r: cylinder radius
 d: cylinder depth

 V = (3) * (3.14) * (4 ^ 2) * (7)
 V = 1055.04 feet ^ 3
 Answer:
 the volume of oil needed is:
 V = 1055.04 feet ^ 3
