Answer:

Step-by-step explanation:

13. All equilateral triangles are acute triangles. An equilateral triangle has three sides of equal length and three equal angles of 60.~ I think it is False.

14. If a triangle has two acute angles, then the third angle must also be acute.~ I think it is true.

15. A triangle cannot be right-angled and obtuse angled at the same time. Since a right-angled triangle has one right angle, the other two angles are acute. Therefore, an obtuse-angled triangle can never have a right angle; and vice versa. ~I think it is false.

Please don't trust me... I hope I helped

I don’t know how to simplify this equation

yanalaym [24]

Answer:

$7^5$

Step-by-step explanation:

According to the Product Rule for Exponents, $\frac{a^m}{a^n} = a^{m-n}$

a = 7

m = 9

n = 4

So,

$\frac{7^9}{7^4} = 7^{9-4} = 7^5$

So, the answer is $7^5$ .

Hope this helps!!!

If SF = 5x + 2, SK = 27, and KF = 3x - 1,<br> find KF.

kondor19780726 [428]

Answer:

KF = 35

Step-by-step explanation:

Since it's a line with K in the middle, we know that the distance SF is the same as SK + KF.

(Start at S, first go to K, then continue to F. You've traveled the same distance as from S to F.)

SF = SK + KF

Let's put in the values we got.

5x + 2 = 27 + (3x -1)

Opening the parenthesis.

5x + 2 = 27 + 3x - 1

5x + 2 = 26 + 3x

Now let's subtract 3x from both sides.

2x + 2 = 26

Now, subtract 2 from both sides.

2x = 24

If we divide by 2...

x = 12

We know that...

KF = 3x -1

Since x is 12, let's put that in.

KF = 3 * 12 - 1 = 36 - 1 = 35

Answer: KF is 35 !
