Answer:

Step-by-step explanation:

use Pythagoras rule

${a}^{2} + {b}^{2} = {c}^{2}$

${5}^{2} + {x}^{2} = { \sqrt{89} }^{2}$

so x = 8

<u>Answer:</u>

Given below.

<u>Explanation:</u>

Coordinates given: W( -4, -3 ) , X( 1 , -2 ), Y(2, -7 ) , Z( -3, -8)

To find the distance we will use the formula: distance=√((x2-x1)²+(y2-y1)²)

WX = √((1--4)²+(-2--3)²)

= √26

YZ = √((-3-2)²+(-8--7)²)

= √26

XY = √((2-1)²+(-7--2)²)

= √26

WZ = √(-3--4)²+(-8--3)²

= √26

WY = √(2--4)²+(-7--3)²

= 2√13

XZ = √(-3-1)²+(-8--2)²

= 2√13

A circular garden has a circumference of 42.3 feet. Find the approximate diameter of the garden. Use 3.14 for π.

tamaranim1 [39]

Answer:

13.5

Step-by-step explanation:

c = 2πr

42.3 = 2(3.14)r

42.3 = 6.28r

6.74 = r

d = r + r

d = 6.74 + 6.74

d = 13.5

A 20 foot ladder leaning against a wall is used to reach a window that is 17 feet above the ground. How far from the wall is the

Liono4ka [1.6K]

Answer:

The wall is 10.5 foot far from the bottom of the ladder.

Step-by-step explanation:

Given:

Height of the ladder leaning against wall (Hypotenuse) = 20 foot.

Height from where the window is above from the ground (Leg1) = 17 feet.

To find the distance of the bottom of the ladder far from the wall (Leg2) = ?

Now, by using the pythagorean theorem:

$Hypotenuse^{2} = (Leg1)^{2} + (Leg2)^{2}$

$20^{2} =17^{2}+(Leg2) ^{2}$

$400=289+(Leg2)^{2}$

$400-289=(Leg2)^{2}$

$111=(Leg2)^{2}$

by squaring both sides

$Leg2=10.535$

10.535 foot rounded nearest tenth is 10.5 foot.

Therefore, the wall is 10.5 foot far from the bottom of the ladder.
