Answer:

<h3>The missing are 8°, 16°, 24°.</h3>

Let the missing angles be x, 2x, 3x.

X + 130° + 2x + 3x = 180°. (sum of angles is 180°)

6x + 130° = 180°

6x = 180°- 130°

6x = 50°

x = 50° ÷ 6

x = 8°

:. 2x = 8 × 2

16°

:. 3x = 8 × 3

24°

1/5+1/7+3/21 the answer is
inessss [21]

Answer:

<h2>17/35</h2>

Step-by-step explanation:

We need to get all the fractions with a common denominator before we can solve the problem.

The only fractions that have a common multiple are 1/7 and 3/21, so we'll add these first and then add 1/5.

1/7 = 3/21

Add

\frac{3}{21} + \frac{3}{21} =\frac{6}{21}

6/21 = 30/105

1/5 = 21/105

\frac{30}{105} + \frac{21}{105} = \frac{51}{105}

Simplify

\frac{51}{105} / \frac{3}{3} =\frac{17}{35}

<h3>ANSWER: 17/35</h3>

I'm always happy to help :)

A circular pool if filling with water. Assuming the water level will be 4' deep and the diameter is 20' , what is the volume of
Yuliya22 [10]

35,569.92 L of water is required to fill the pool

Step-by-step explanation:

  • Step 1: Find the area of the circular pool when radius = 20/2 = 10 ft

⇒ Area = πr² = 3.14 × 10² = 314 ft²

  • Step 2: Find the volume of the pool

Volume = Area × Depth

             = 314 × 4 = 1256 ft³

  • Step 3: Convert the volume into liters.

Volume of water = 1256 × 28.32 = 35,569.92 L (∵1 ft³ = 28.32 L)
