Answer:

m=0.7404, b=3.9117m=0.7404,b=3.9117

y=0.7404x+3.9117y=0.7404x+3.9117

x=18x=18

y=0.7404(18)+3.9117=17.2389y=0.7404(18)+3.9117=17.2389

Residual

16-17.2389= -1.238916−17.2389=−1.2389

3. Is XY Tangent to circle Z?<br> Y<br> 12 X<br> (20<br> Z<br> 18

Ratling [72]

Answer:

XY is a tangent

Step-by-step explanation:

Given

$XY = 12$

$WY = 20$

$WZ = 8$

Required

Is XY a tangent?

XY is a tangent if:

$WY^2 = XY^2 + WX^2$

Because XY should make a right angle at point X with the circle

Where

$WX = 2 * WZ$

So, we have:

$WY^2 = XY^2 + WX^2$

$WY^2 = XY^2 + (2*WZ)^2$

$WY^2 = XY^2 + (2WZ)^2$

$WY^2 = XY^2 + 4WZ^2$

This gives:

$20^2 = 12^2 + 4*8^2$

$400 = 144 + 256$

$400 = 400$

<em>Yes, XY is a tangent</em>

Can someone help me.

Sauron [17]

Answer:

The answer to your question is: 20°

Step-by-step explanation:

Data

m∠XZY = 40

m∠XZB = 20

Process

1.- Find the measure of ∠ XAB

∠XAB = 40° because AB ║ YZ

2.- Find the measure of ∠ZAB

∠ZAB + ∠XAB = 180

∠ZAB = 180 - ∠XAB

∠ZAB = 180 - 40

∠ZAB = 140°

3.- Find the measure of ∠ABZ

The sum of the internal angles in a triangle equals 180°

∠AZB + ∠ZAB + ∠ABZ = 180

20° + 140° + ∠ABZ = 180

∠ABZ = 180 - 20 - 140

∠ABZ = 20°

How to find the area of a square ABC D

____ [38]

Answer:

The answer to your question is 13 u²

Step-by-step explanation:

We know that the small triangle is surrounded by right triangles so we can use the Pythagorean theorem to find the lengths of the small triangle

AD² = 3² + 2²

Simplify

AD² = 9 + 4

AD² = 13

AD = $\sqrt{13}$

Find the area of the square

Area = side x side

Area = AD x AD

Area = $\sqrt{13} x \sqrt{13}$

Area = 13 u²
