Yuliya22 [10]

Answer:

An expected height of 160.6 centimeters when the femur has a length of 40 centimeters.

Step-by-step explanation:

The line of best fit makes a prediction. In other words, it tells us what height to expect for any given femur length.

x represents femur length and y represents height, so the y-value on the line when x=40x is the expected height when the femur length is 40 cm.

Geometry Special Quadrilaterals show work please
Charra [1.4K]

Answer:

a = 16

w = 125

x = 120

y = 55

Step-by-step explanation:

<u>FINDING 'a'</u>

31 = a + 46 / 2

62 = a + 46

16 = a

<u>FINDING 'w'</u>

* This section looks Non-Isosceles trapezoid so I will be following the rule according it

w + 55 = 180

w = 125

<u>FINDING 'y'</u>

y = 55

- Because of corresponding angles

<u>FINDING 'x'</u>

* In this case it looks like we are still dealing w/ an non-isosceles trapezoid.

x + 60 = 180

x = 120

Hope this helped ^^

(Please inform me of any mistakes or misunderstandings!)

Write and solve the equation to find the value of x and the missing angle measures.​
MrRissso [65]

Answer:

x = <u><em>8</em></u>

The missing measures are <em><u>85</u></em> degrees

Step-by-step explanation:

Since 9x + 13 and 11x - 3 are on opposite sides, they are equal, so

9x + 13 = 11x - 3

Subtract 13 from both sides:

9x = 11x - 16

Subtract 11x from both sides:

-2x = -16

Divide both sides by -2:

x = 8

The angle measures are

9(8) + 13 = 72 + 13 = 85

11(8) - 3 = 88 - 3 = 85
