6 0

They are because if two angles that have a side of one triangle that is congruent to the corresponding parts of another triangle, the triangles are congruent to the corresponding altitudes in triangles.

Can someone help please

lutik1710 [3]

Step-by-step explanation:

For no. 8

2x + 1°+ 33° = 90° { Being complementary angles }

2x + 34° = 90°

2x = 90° - 34°

2x = 56 °

x = 56° / 2

x = 28°

For no. 10

5x + 12 = 6x - 10 ( being vertically opposite angles)

6x - 5x = 12 + 10

x = 22

Hope it will help :)❤

Answer:

12709 balls

Step-by-step explanation:

Given

Dimension of Room = 15 ft by 20 ft by 10 ft

Diameter of Ball = 9.2 inches

Required

Determine the number of balls that can be occupied by the room

First, we need to calculate the volume of the room

This is done by multiplying the dimensions of the room

$Volume = 15ft * 20ft * 10ft$

$Volume = 3000ft^3$

Next, we calculate the volume of the ball.

The ball is a sphere.

So:

$Volume = \frac{4}{3}\pi r^3$

Where

$r = \frac{1}{2} * Diameter$

$r = \frac{1}{2} * 9.2$

$r = 4.6\ in$

So:

$Volume = \frac{4}{3}\ * \frac{22}{7} * (4.6in)^3$

$Volume = 407.88419\ in^3$

To calculate the number of balls, we then divide the volume of the room by volume of a ball

$Balls = \frac{3000\ ft^3}{407.88419\ in^3}$

Convert ft^3 to in^3

$Balls = \frac{3000 * 1728in^3}{407.88419\ in^3}$

$Balls = \frac{3000 * 1728}{407.88419}$

$Balls = \frac{5184000}{407.88419}$

$Balls = 12709.4899167$

$Balls = 12709$ <em>-- approximated</em>

<em>Hence, the room will contain 12709 balls</em>
