Answer:

AX = 14

Step-by-step explanation:

The medians of a triangle intersect at its centroid.

The position of the centroid X from the vertex A is

AX = $\frac{2}{3}$ AL = $\frac{2}{3}$ × 21 = 14

(7)8 - 6 divided by 2 + (A)3 = 107. What is A?

Hunter-Best [27]

$\huge\fbox{Answer ☘}$

$7(8) - 6 \div 2 + (a)3 = 107 \\ 56 - 3 + 3a = 107 \\ 53 + 3a = 107 \\ 3a = 107 - 53 \\ 3a = 54 \\ a = \cancel\frac{54}{3} = 18$

hope helpful~

Heather measures the temperature of her coffee to be 133.4 degrees fahrenheit. It is actually 145 degrees fahrenheit. What is th

zhenek [66]

Answer:

The percent error of Heather's calculation is 8%.

Step-by-step explanation:

Given:

Heather measures the temperature of her coffee to be 133.4 degrees fahrenheit. It is actually 145 degrees fahrenheit.

Now, to find the percent error of Heather's calculation.

The temperature of coffee Heather measures = 133.4° F.

Coffee's actual temperature = 145° F.

So, to get the measurement in error we subtract the temperature of coffee Heather measures from coffee's actual temperature:

$145-133.4=11.6\°.$

Now, to get the percent error:

$\frac{11.6}{145}\times 100$

$=\frac{1160}{145}$

$=8\%.$

Therefore, the percent error of Heather's calculation is 8%.

Triangle FGH is equilateral. The midpoints of the sides are connected to form triangle XYZ. Line segment XY is parallel to line

Hatshy [7]

Answer:

Isosceles trapezoid

Step-by-step explanation:

The figure will look like one large triangle on the outside and four smaller triangles on the inside. you are only concerned with the inside triangle that is pointing to the line FH. Since XY and FH are parallel and the distance between FX and YH are equivalent (the midpoints of each side should be the same for all three sides of the larger triangle) the shape FXYH is an isosceles trapezoid.

A movie theater has a 24-foot-high screen located 6 feet above your eye level. If you sit x feet back from the screen, your vi

pantera1 [17]

Answer:

The viewing angles are as follows:

For x=5 feet, θ = 0.529 radians

For x=10 feet, θ = 0.708 radians

For x=15 feet, θ = 0.726 radians

For x=20 feet, θ = 0.691 radians

For x=25 feet, θ = 0.640 radians

Step-by-step explanation:

The viewing angle is given as:

θ = tan⁻¹(30/x) - tan⁻¹ (6/x)

where x is the distance between you and the screen.

The question is asking us to find the viewing angle θ at various distances. The distance value needs to be substituted in the above equation in place of x. So,

For x=5 feet:

θ = tan⁻¹(30/5) - tan⁻¹ (6/5)

= 1.4056 - 0.8761

θ = 0.529 radians

For x = 10 feet:

θ = tan⁻¹(30/10) - tan⁻¹ (6/10)

= 1.249 - 0.540

θ = 0.708 radians

For x = 15 feet:

θ = tan⁻¹(30/15) - tan⁻¹ (6/15)

= 1.107 - 0.380

θ = 0.726 radians

For x = 20 feet:

θ = tan⁻¹(30/20) - tan⁻¹ (6/20)

= 0.983 - 0.291

θ = 0.691 radians

For x = 25 feet:

θ = tan⁻¹(30/25) - tan⁻¹ (6/25)

= 0.876 - 0.235

θ = 0.640 radians
