Answer:

See below.

Step-by-step explanation:

1) Please check the number of volume of steel. It should be 54,259.2

${cm}^{3}$

. Not 54,259.2 cm. Right?

2) If so,

First

The volume of single rod

$= \pi \times ( { \frac{4}{2} })^{2} \times 60= \pi \times {2}^{2} \times 60= 4\pi \times 60= 4 \times 3.14 \times 60= 753.6 {cm}^{3}$

The number of rods

$= \frac{54259.2}{753.6} = 72$

I need help with help on the one with the pink circle

Answer:

15°

Step-by-step explanation:

The line in the middle of the triangle divides it into two triangles. These two triangles are equal. You can see this because the given angle (90°) is equal for both sides, and the bottom sides (23) are also equal to each other.

Since the triangles are equal, this means that the given angle of 75° also applies to the other side. The total degrees a triangle can have is 180°. Use the given angles to solve for the unknown angle.

75° + 90° + x = 180°

165° + x = 180°

x = 15°

The angle measure will be 15°.
