What is the area of ​​a triangle ABC with AB=AC=5cm and BC=6cm?

Mathematics
1 answer:
Vika [28.1K]1 year ago
8 0

Answer: 12 cm^2

Step-by-step explanation:

BC ==> Base of triangle

Divide the triangle in two parts:

BC/2=BC'

6/2=BC'

BC'=3

Distance formula: a^2+b^2=c^2

c^2-a^2=b^2

5^2-3^2=b^2

25-9=b^2

b^2=16

b=4 ==> height of triangle

Area of triangle=A. b=base. h=height

A=1/2 * b * h=

A=1/2 * 6 * 4

A=1/2 * 24

A=12 cm^2

Alexeev081 [22]

Answer:

There are 23 cats for every 36 dogs at the city pound

Step-by-step explanation:

This means that for every group of 92 cats at the city compound there is a group of 144 dogs. So it also means that for every group of 23 cats there is a group of 36 dogs.

92 to 144 or 92/144 = 23/26  or 23 to 36

LM = 9, NR = 16, SR = 8. Find the perimeter of triangle LRN.
sweet [91]
<h2>D. 50 units</h2>

Hi, I’m Lena and I will be answering your question to the best of my ability. If you have any further questions after my answer, do not hesitate to ask me! ツ

♡ Let’s look at the main important thing(s) that will lead you in the correct path.

♥ The perimeter is the outside, it is <em>around</em> the figure. When you see those inner triangles, do not pay attention to them! They are just there to make your overthink the question.

♡ Let's solve!

♥ To begin, let's take LM. It already gives you half the segment, so all you need to do is double the number. 9*2=18.

♥ Now, let's take a look at NR. They already give you the segment as a whole, so you do not need to worry about it!

♥ Look at SR. You do the same thing as you did to LM, double the number. 8*2=16.

Now, we add all the numbers to get our final answer.

18+16+16=50.
