Find angles EFG pleaseee

Bumek [7]

Answer:

50 degrees.

Step-by-step explanation:

Angle FGE = $180-(7x+18)$ because angles on a straight line add up to 180 degrees.

Angle EFG = $180-38-(180-(7x+18))=6x-10$ (Angles in a triangle add up to 180)

$180-38-\left(-7x+162\right)=6x-10$

$180-38+7x-162=6x-10$

$7x-20=6x-10$

Add 20 to both sides:

$7x-20+20=6x-10+20$

$7x=6x+10$

Subtract 6x from both sides:

$7x-6x=6x+10-6x$

$x=10$

Angle $EFG=6x-10=6(10)-10=60-10=50$

The volume of a spherical tank is 790.272 pie cubic feet what is the diameter of the container

pochemuha

Answer:

The diameter is 13.88 feet.

Step-by-step explanation:

1. The formula for calculate the volume of a sphere is:

$V=\frac{3}{4}(r^{3}\pi)$

Where $r$ is the radius.

2. The diameter is:

$D=2r$

3. So, you must solve for the radius in the first equation:

$r=\sqrt[3]{\frac{4V}{3\pi}}$

$r=\sqrt[3]{\frac{4(790.272ft^{3} )}{3\pi}}\\r=6.94ft$

4. Then, the diameter is:

$D=2(6.94ft)\\D=13.88ft$
