A triangle has 2 sides that are 9 inches and the bottom is 6 inches what is the height?
Elanso [62]

The height of the isosceles triangle is 8.49 inches.

<h3>How to find the height of the triangle?</h3>

Here we have a triangle such that two of the sides measure 9 inches, and the base measures 6 inches.

So this is an isosceles triangle.

We can divide the isosceles triangle into two smaller right triangles, such that the side that measures 9 inches is the hypotenuse, the base is 3 inches, and the height of the isosceles triangle is the other cathetus.

By Pythagorean's theorem, we can write:

(9in)^2 = (3 in)^2 + h^2

Where h is the height that we are trying to find.

Solving that for h we get:

h = √( (9 in)^2 - (3in)^2) = 8.49 inches.

We conclude that the height of the isosceles triangle is 8.49 inches.

Finding Distance in the Coordinate Plane
GuDViN [60]

The distance between the two points (-1, 4) and (5, 4) is 6 units.

<u>Step-by-step explanation:</u>

The given Coordinate points are (-1, 4) and (5, 4).

The points are considered as (x1,y1) and (x2,y2).

Here,

x1 = -1 and x2 = 5

y1 = 4 and y2 = 4

<u>The distance formula is given by :</u>

Distance = \sqrt{(x2-x1)^2+(y2-y1)^2}

<u>To find the distance between these two points :</u>

The distance formula is used,

Distance = \sqrt{(5+1)^2+(4-4)^2}

⇒ √(6)²

⇒ √36

⇒ 6

Therefore, the between the points is 6 units.
