3 0

If you need to find the length of the hypotenuse of a right triangle, you can use the Pythagorean theorem if you know the length of the other two sides. Square the length of the 2 sides, called a and b, then add them together. Take the square root of the result to get the hypotenuse.

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.

What is the value of cos-1 (-√3/2

melamori03 [73]

Answer:

Step-by-step explanation:

This question is asking you "what angle gives you a cos of -square root 3/2"? The cosine by definition is the side adjacent to the angle over the hypotenuse. So set up the right triangle. We do not know which quadrant we are in since we are not told that, but if the cos is negative, then we are in either QII or QIII. In QII this is a 150 degree angle, and in QIII this is a 210 degree angle.
