Answer:

C) 8+x > 10

Step-by-step explanation:

I think C is the correct answer because it's an open circle, it can't equal to 2 and it must be higher than 2.

<u>Answer</u>:-

Q no.8 :

9, 13, 17 can merely be the correct option.

Explanation:-

• The Triangle Inequality Theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third.

For instance:-

1) Calculation: 9 + 13 = 22 which is greater than the third side (the hypotenuse) that was 17. And hence is correct.

2) Calculation: 10 + 10 = 20 which is equal to the third/hypotenuse side that was also 20. Therefore it doesn’t fit the theorem and is unable to form a triangle.

3)Calculation: 6+8 = 14 which is less than the greatest/hypotenuse/third side or the side of measure 15. Thence, it isn’t the correct also. No accurate triangle can be formed from all these(6, 8, 15) measurements.

4) Calculation: 2+3 = 6 which is equal to the third /hypotenuse side of measure 6 also. And therefrom no triangle can be constructed from the given sides(2, 3, 6).

• The third important property of triangles is the triangle inequality rule, which states:

“The length of a side of a triangle is less than the sum of the lengths of the other two sides and greater than the difference of the lengths of the other two sides”.

(Note: I honestly prefer you to understand from the first point which is far much clearer than the second one).

Please help just looking for the answer

Answer: Correct Answer is 4th option , 28

Step-by-step explanation:

We can find the measure of the angle using the tangent.

We know, tangent of an angle = Perpendicular/Base, corresponding to that angle.

So, Tan of angle T = RG / RT

or, Tan of angle T = 8/15

or, angle T = tan inverese of 8/15

or, angle T = 28.07

So, angle T rounded to nearest degree = 28

Hope this helps.

Thank you.

43/645= I need the to show the work

Licemer1 [7]

I'm guessing you need 43/645 simplified:

First, we need to find the greatest common factor (GCF) of the numerator (43) and the denominator (645). To do so, we list all the factors of each number and find the common ones.

Factors of 43: 1, 43
Factors of 645: 1, 3, 5, 15, 43, 129, 215, 645

Out of the listed factors for each number, which numbers are common between the two? The common factors are 1 and 43. Since we are looking for the GREATEST common factor, which number out of 1 and 43 is the greatest? The GCF is 43.

Second, we can now divide the numerator (43) and the denominator (645) by the GCF we recently found which was 43.

$43 \div 43 = 1 \\ 645 \div 43 = 15$

Third, our new simplified fraction is 1/15. We collected our new numerator and denominator.
