Answer:

Option (4)

Step-by-step explanation:

Vertical angles theorem;

"Two vertically opposite angles formed by the intersection of two straight lines are congruent"

By this theorem,

If ∠1 and ∠2 are the vertical angles                            Given

∠1 ≅ ∠2                                                                Vertical angles theorem

Therefore, Option (4) is the correct option.

Use the Pythagorean Theorem to find the distance of the missing side. (I’m sorry I need help with the whole thing)
Maurinko [17]

Answer:

1: 5.83

2: 4.12

3: 3.61

4: 5

5: 6.32

6: 5.10

Step-by-step explanation:

The Pythagorean theorem is a^2 + b^2 = c^2

For all of these you can count the number of blocks over to find two sides of the triangle.

For example: the first one has two sides, one is 3 units, the other is 5. To find the missing angle you square 3 and 5, then add that together. That is equal to 34. 34 = c^2. To get the c by itself, you then take the square root of 34. So the missing side (c) is equal to 5.83.

What two numbers multiply to 20 and add up to 17
Shalnov [3]
That is not possible, since 20 has the factors of 1,2,4,5,10, and 20. None of those add up to 17, maybe your question has a mistake in it. For further questions, you can message me. Hope this helps! Please rate brainiest answer.

8. Don made deposits of $500 at the end of each year for eight years. The rate is 8% compounded annually. Using the tables found
Sonbull [250]

Answer:

Step-by-step explanation:

P = $ 500 ;r =8% ;  n= 8

A = P* (1+r/100)^n

A= 500 * ( 1 + 8/100)⁸

= 500 * ( 1 + 0.08)⁸  = 500 * 1.08⁸

=500*1.85

= $ 925.45
