Find the value of x in the<br> isosceles triangle shown below.<br> Help plzzzz

zysi [14]

Answer:

x =2

Option D is correct !!!

Step-by-step explanation:

By Pythagoras theorem we can solve this

we know that:

${x}^{2} + {4}^{2} = \sqrt{20} {}^{2}$

${x}^{2} = \sqrt{20} ^{2} - 16$

${x}^{2} = 20 - 16$

$x = 2$

Identify the relation that is also a function. A. {(-1, 1) (0, 0) (1, 1) (2, 4)} B. {(3, 4) (2, 3) (3, 6) (2, 0)} C. {(1, 0) (2,

madreJ [45]

Answer:

Step-by-step explanation:

We are given four sets of relations as

$A. {(-1, 1) (0, 0) (1, 1) (2, 4)} \\B. {(3, 4) (2, 3) (3, 6) (2, 0)} \\C. {(1, 0) (2, 3) (3, -2) (1, 6)} \\D. {(3, 2) (3, -2) (3, 6) (3, 8)}$

A function is a relation in which every element in the first set has a unique image in the second set.

Let us check this aspect to A.

This is a function

Now come to B. 3 has two images 4 and 6. so not a function

Next is C. in C 1 has two images 0 and 6. So not a function

For D, 3 has 4 images so not a function.

The perimeter of the rectangle below is 64 units. Find the length of side CD.

ahrayia [7]

Answer:

CD = 18 units

Step-by-step explanation:

Given a rectangle with length x and width y, the perimeter is:

P = 2x + 2y

Here, we note that x = AB = CD, y = AD = BC, and P = 64 units. So:

2AB + 2BC = 64

We know that AB = 3z and BC = 2z + 2; plug these in:

2 * (3z) + 2 * (2z + 2) = 64

6z + 4z + 4 = 64

10z = 60

z = 6

Now that we've solved for z, we can find AB and, hence, CD because AB = CD.

AB = 3z = 3 * 6 = 18 units

Thus, CD = 18 units, as well.
