Answer:

P(−2, 5), Q(−8, −2)

=> v = PQ = ( -8 - -2, -2 - 5) = (-6, -7)

I do not think there are any. If you used -20 and 2, which would be close to 16, the sum would be 18.

If BC= 48 cm and sin

Using relations in a right triangle, it is found that the length of AC is of 14 cm.

<h3>What are the relations in a right triangle?</h3>

The relations in a right triangle are given as follows:

The sine of an angle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.

The cosine of an angle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.

The tangent of an angle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.

Researching this problem on the internet, we have that:

The opposite leg to angle A is of 48 cm.

sin(A) = 0.96.

Hence the hypotenuse is found as follows:

sin(A) = 48/h

0.96 = 48/h

h = 48/0.96

h = 50 cm.

The length of side AC is the other leg of the triangle, found using the Pythagorean Theorem, hence:

$x^2 + 48^2 = 50^2$

$x^2 = \sqrt{50^2 - 48^2}$

x = 14 cm.

Please I need help step by step

Perimeter = 18.9

If you observe the triangle, you can see that all of its sides are equal. They are all s, or 6.3 mm. This means that to find the perimeter of the triangle, you can do either of two things:

1. You can multiple s by 3.

2. You can add s three times.

Either way, you will get the same answer. 6.3 • 3 = 18.9, and 6.3 + 6.3 + 6.3 = 18.9

If I am understanding the question correctly, then "type" means the type of triangle this triangle is. To figure this out, look at the measurements of the triangle. All of its sides are equal in length. That means that it is an equilateral triangle.

I know some schools like students to write "equilateral acute" triangles, since all of the angles are less than 90˚. If you want to be sure, I'd contact your teacher and ask.

Hope this helps!
