Answer:

x = 2√5

Step-by-step explanation:

Using the Pythagorean Theorem:

a² + b² = c²

You can identify that x is the hypotenuse, as it is opposite to the right angle.

So:

3² + √11² = x²

9 + [(√11) (√11)] = x²

9 + 11 = x²

20 = x²

√20 = √x²

√4√5 = x

2√5 = x

x = 2√5

Use the following ordered pairs

Lynna [10]

The ordered pair for Y is (-4,-2)

Step-by-step explanation:

Given

X(-2,3)

Z(-6,-7)

As Y is the mid-point of XZ, it will divide Xz in two equal segments. Y is the mid-point of the segment.

Let (x_Y, y_Y) be the coordinates of the mid-point

Then

$(x_Y, y_Y) = (\frac{x_1+_2}{2} , \frac{y_1+y_2}{2})$

Putting the values

$=(frac{-2-6}{2} , \frac{3-7}{2})\\=(\frac{-8}{2} , \frac{-4}{2})\\=(-4, -2)$

Hence,

The ordered pair for Y is (-4,-2)

Find surface area of the right angled triangular prism.

jeka57 [31]

A triangular prism has 5 faces, 3 being rectangular and 2 being triangular. The area of the rectangular faces can be found by multiply the base and height lengths together. The area of the triangular faces can be found by multiplying the base and height and dividing by 2.
