In right triangle ABC, angle C is a righ angle, AB=13, and BC=5 .what is the length of AC?

Answers

Answer 1

Answer:

12

Step-by-step explanation:

Since this is a right triangle you can you pythagorean theorem.

a^2+b^2=c^2

A= shortest side.

B=middle side.

C=longest/slanted side or hypotenuse.

So AB is the hypotenuse.

BC is the short side.

this means that AC is the middle side. Plug your numbers in.

25 + b^2 =169

b^2=144

b=12

AC=12

Step-by-step explanation:

Step 1: Define

f(t) = t² - 2t

f(-7) is t = -7

Step 2: Solve

Substitute:                         f(-7) = (-7)² - 2(-7)Exponents:                        f(-7) = 49 - 2(-7)Multiply:                             f(-7) = 49 + 14Add:                                   f(-7) = 63

Which of the following additional statements would you need to prove these two triangles are similar by SAS similarity?

1. ∠A ≅ ∠D
2. ∠B ≅ ∠E
3. ∠B ≅ ∠F
4. ∠C ≅ ∠F

Answers

Answer:

option 1

as the sides were already given, A and D are the only way that the triangle can have SAS.

The option 1 . ∠A ≅ ∠D is correct and needed to apply SAS similarity theorem in this given condition.

What is SAS (side angle side ) similarity theorem for two triangles?

The  SAS theorem states that if two triangles have a congruent angles and the sides that define the angle  are proportional, the two triangles are similar.

Given are two triangles ΔABC and ΔDEF and their sides AB =7 , AC = 12, DE =14, DF = 24

Then AB/ DE = 7/14 = 1/2

 and AC / DF = 12/24 = 1/2

∴ AB / DE = AC/ DF

Therefore the sides AB and AC are proportional to DE and DF

And for the application of SAS the angle defined by these pairs must be congruent.

AB and AC defines ∠A and DE and DF defines ∠D

Thus, ∠A must  be congruent to  ∠D so that SAS can be to applied to make the given triangles similar.

Therefore, option 1. ∠A ≅ ∠D  is correct option

​

Answers

Answer:

  5 and 15

Step-by-step explanation:

Let x represent the smaller number. Then the larger is x+10. The sum is ...

  2x +3(x+10) = 55

  5x +30 = 55

  5x = 25

  x = 5

The two numbers are 5 and 15.

Hamid has gained weight.
He now weighs 88kg, whish is higher than his normal weight
What is Hamid's normal weight?

Answers

The situation we have to find is how much weight Hamid has gained. There is no number so I’m just going to teach u how to find the original weight. So basically you have to subtract the weight that is gained from the current weight which will give you the answer to the normal weight.
Current weight-weight gained=normal weight
For example if he gained 5 kg
88-5=83 so his normal weight is 83kg
