The coordinates of triangle GBW are G (20, 10) B (-35, 20), and W (5,-10). Is GBW a right triangle? Justify your answer.

Answers

We know from Pythagoras' Theorem, a right angle triangle can be identified by the relationship:

$a^2+b^2=c^2$

Thus, we know if the side lengths of the triangle in question abide by this relation, the triangle is right.

First, we must find the greatest side length.

We know, using the distance formula.

$GB= √((-35-20)^2 +(20-10)^2) =√(3125)$
$BW= √((5+35)^2 +(-10-20)^2) =√(2500)$
$WG= √((20-5)^2 +(10+10)^2) =√(625)$

From this, we know that:
$GB\ \textgreater \ BW\ \textgreater \ WG$
Therefore, GB would be the hypotenuse of the triangle.
Now we substitute the values for the two shorter lengths and the greater length into the pythagorean theorem:
$a^2+b^2=2500+625=3125$
$c^2=3125$
$\therefore LHS=RHS$
Therefore, this triangle is a right angled triangle

How to convert 25.12% into a fraction of 10,000

Answers

Answer:

25.12/100

Step-by-step explanation:

Percent means per hundred, so 25.12 percent means 25.12 per hundred. Thus, you can make 25.12 the numerator and 100 the denominator, and make 25.12 percent a fraction like this:

25.12/100

Should you use Sine, Cosine, Tangent to solve the following problem

Answers

We will use Tangent of the angle.

What is Tangent of the angle?

In trigonometry, the tangent of an angle is the ratio of the length of the opposite side to the length of the adjacent side.

Given that, a right triangle, with perpendicular = x and an acute angle = 28° and base = 14

Since, we know that, tan α = opposite side / adjacent side

In other two trigonometric ratios, we need the length of hypotenuse, which is not given.

Hence, We will use the Tangent of the angle.

Answer:

tangent

Step-by-step explanation:

SOH( sin = opposite/hypotenuse)

CAH(cosine = adjacent/hypotenuse)

TOA(tan = opposite/adjacent)

you are trying to find x and the numbers given to you are opposite of x and adjacent to x. that means you need to use toa

A book shows an enlarged photo of a carpenter bee. A carpenter bee is about 6×10^-3 m long. The photo is 13.5 cm long. About how many times as long as a carpenter bee is the photo?

Answers

A ratio compares values. A ratio says how much of one thing there is compared to another thing. We do as follows:

length of photo/ length of a carpenter bee = ratio of the two
13.5 / 6x10^-3 = 2250

Therefore, the photo is 2250 longer than the carpenter bee.
