Answer:

Step-by-step explanation:

So, lets go over what we know.

One side length is 28.

The other side length is 21.

The missing hypotenuse(longest length) is x.

We can use the pythagreons theorm to find x:

A^2+B^2=C^2. Remember that the two smaller side lengths are A and B, while the longest side length(in this case x) is C.

Plugging in our values:

28^2+21^2=x^2

Distrubute the ^2:

784+441=x^2

Combine the two side lengths:

1225=x^2

Now square root both sides to get x^2 alone(as x)

35=x

So our missing side length, x, is 35!

Hope this helps! :D

How Do I do proofs for proving triangles?

MA_775_DIABLO [31]

You must have been taught postulates and theorems that allow you to prove triangles congruent, such as SSS, SAS, ASA, etc. Look at the given information of a proof, and see how from the given information, using definitions, postulates, and theorems you have already learned, you can show pairs of corresponding sides and angles to be congruent that will fit into the above methods. Then use one of the methods to prove the triangles congruent.

If ABCD congruent to QRST, measure of angle A = x – 10º, and measure of angle Q = 2x – 30º, what is the measure of angle A?

belka [17]

Congruent means they are the same,

A and Q are both the first letters, which mean they would also be the same.

Set the two equations equal to each other, solve for x then solve for angle A.

x-10 = 2x-30

Add 30 to each side:

x+20 = 2x

Subtract 1x from each side:

x = 20

Now replace x with 20 in the equation for A

A = 20-10

Angle A = 10 degrees.

KonstantinChe [14]

Per round there are a certain amount of teams which cuts the amount of games in half. For Example, in the first round there are 64 teams which cuts the amount of games in half to 32 games. This will keep occurring until there are only 2 teams left with one game (This declares the winner).

First round:

64 teams

32 games

Second round:

32 teams

16 games

Third round:

16 teams

I am one of the numbers represented on a number line when you divide the segment between -15 and 25 into 4 equal parts. I am pos

Aliun [14]

Answer:

2, 3, 5, 7, 11, 17, 19, 23

Step-by-step explanation:

The segment between - 15 and 25 has 40 numbers given by

25 - -15

= 25 + 15

= 40

Divided into 4 segments, each would contain 10 numbers such that the

1st segment is from -15 to -5 (which is -15 + 10)

2nd segment is from -5 to 5 (which is -5 + 10)

3rd segment is from 5 to 15 (which is 5 + 10)

4th segment is from 15 to 25 (which is 15 + 10)

Given that the unknown number is prime and positive this may be

2 or 3 or 5 from the 2nd segment

7 or 11 from the third segment

17 or 19 or 23 from the 4th segment
