What kind of triangle would the measurements 7ft 15ft 17ft
devlian [24]

Answer:

This is an Obtuse triangle.

Step-by-step explanation:

A Equilateral Triangle is a triangle where all sides are equal. Here all sides are different so it is not an Equilateral Triangle.

Isosceles triangle is a triangle that has 2 sides that are equal. Here all sides are different therefore this is not an Isosceles triangle.

A right angled triangle is a triangle whose sides satisfy the following equality.

Lets say A triangle has sides a, b and c. Where c is the highest value.

Then, a^{2} +b^{2} =c^{2}

Lets substitute the values to the above equation to see whether it the triangle we are given satisfies the above equality,

7^{2} +15^{2} = 49+225=274

17^{2} =289

Therefore, 7^{2} +15^{2} ≠17^{2}So it is not a Right Angled Triangle.If the sum of squares of the shorter sides is greater than the square of the longer side then it is an Acute angle if not it is an obtuse angle.[tex]7^{2} +15^{2} = 274≤17^{2} =289

Therefore, This is an Obtuse triangle.

Which binomial is a factor of 100x2 – 49?
pentagon [3]

Answer:

Step-by-step explanation:

What you have here is called "the difference of two squares"

Difference means subtraction and both 100x2 and 49 are perfect squares.

The factored form of 100x2-49 is

(10x+7)(10x-7)

Because 10x times 10x is 100x2 and 7 times 7 is 49

One factor has a + and

One factor has a -

It is a pattern worth memorizing!

So 10x + 7 is the factor you're looking for.
