I am stuck on 14 and 15 as they do not have a straight line going through to help me, anybody know how to ?? thanks !

Answer:

14. x=21, GK=167°, HJ=98°, HGJ=262°, GKJ=201°

15. x=9, AD=108°, BC=23°, DC=139°, DBC=221°

Step-by-step explanation:

In each case, the sum of the arcs around the circle is 360°.

14. 61 +(5x -7) +34 +(9x -22) = 360

14x = 294 . . . . . subtract 66, simplify

x = 21 . . . . . . . . divide by 14

(5x -7) = 98

(9x -22) = 167

x = 21
arc GK = 167°
arc HJ = 98°
arc HGJ = 360° -98° = 262°
arc GKJ = 167° +34° = 201°

15. 90 +(2x +5) +(17x -14) +(12x) = 360

31x = 279 . . . . subtract 81, simplify

x = 9 . . . . . . . . divide by 31

(2x+5) = 23

(17x -14) = 139

(12x) = 108

x = 9
arc AD = 108°
arc BC = 23°
arc DC = 139°
arc DBC = 360° -139° = 221°

*27 POINTS PLEASE HELP*

To compute the slope of a segment, given its endpoints $A(A_x,A_y),\ B=(B_x,B_y)$ , you write

$m_{AB} = \dfrac{A_y-B_y}{A_x-B_x}$

Given this formula, you have the four slopes:

$m_{AB} = \dfrac{A_y-B_y}{A_x-B_x} = \dfrac{-1-2}{-4+1} = \dfrac{-3}{-3} = 1$

$m_{BC} = \dfrac{B_y-C_y}{B_x-C_x} = \dfrac{2-1}{-1-5} = \dfrac{1}{-6} = \dfrac{-1}{6}$

$m_{CD} = \dfrac{C_y-D_y}{C_x-D_x} = \dfrac{1+3}{5-1} = \dfrac{4}{4} = 1$

$m_{DA} = \dfrac{D_y-A_y}{D_x-A_x} = \dfrac{-3+1}{1+4} = \dfrac{-2}{5} = -\dfrac{2}{5}$

Now, two segments are parallel if they have the same slope. So, AB and CD are parallel, because they both have slope 1, but BC and DA are not parallel.

This means that ABCD is not a parallelogram, because in parallelograms the opposite sides are parallel.

The angle of elevation from a soccer ball on the ground to the top of the goal is 34. If the goal is 8 feet tall, What is the di

damaskus [11]

Answer:

The distance from he ball to the goal is 11.85 feet (Approx) .

Step-by-step explanation:

As given

The angle of elevation from a soccer ball on the ground to the top of the goal is 34° .

If the goal is 8 feet tall.

Now by using the trigonometric identity .

$tan \theta = \frac{Perpendicular}{Base}$

As shown in the diagram given below

$\theta = 34^{\circ}$

Perpendicular = AB = 8 feet

Base = BC

Put all the values in the identity .

$tan\ 34^{\circ} = \frac{AB}{BC}$

$tan\ 34^{\circ} = \frac{8}{BC}$

$tan\ 34^{\circ} = 0.675\ (Approx)$

$BC = \frac{8}{0.675}$

BC = 11.85 feet (Approx)

Therefore the distance from he ball to the goal is 11.85 feet (Approx) .
