The cross section of a hopper for containing balls is shown.
svp [43]
ANSWER

14 \: ft



EXPLANATION

Let the top of the hopper be

l \: ft


Then, by the cosine rule,

{l}^{2}  =  {13}^{2}  +  {15}^{2}  - 2(15)(13) \cos(59.5 \degree)

We evaluate to get,

{l}^{2}  =  169 + 225    - 390\cos(59.5 \degree)


{l}^{2}  =  394  - 197.94



{l}^{2}   = 196.06
Take positive square root of both sides to get,



l =  \sqrt{196.06}


l = 14.00

HJ= 5x -3, JK= 8x -9 and KH= 131
Fynjy0 [20]

Answer:

HJ = 52

JK = 79

Step-by-step explanation:

Hello, I want to assume you are trying to determine either HJ or JK. Below is an illustration of how to determine either HJ or JK.

From the question given above, the following data were obtained:

HJ = 5x – 3

JK = 8x – 9

KH = 131

If we draw a straight line, we'll observe the following:

H_______J_______K

KH = HJ + JK

Next, we shall determine the value of x.

HJ = 5x – 3

JK = 8x – 9

KH = 131

KH = HJ + JK

131 = (5x – 3) + (8x – 9)

131 = 5x – 3 + 8x – 9

Collect like terms

131 + 3 + 9 = 5x + 8x

143 = 13x

Divide both side by 13

x = 143 / 13

x = 11

Finally, we shall determine HJ and JK. This can be obtained as follow:

For HJ:

HJ = 5x – 3

x = 11

HJ = 5(11) – 3

HJ = 55 – 3

HJ = 52

For JK:

JK = 8x – 9

x = 11

JK = 8x – 9

JK = 8(11) – 9

JK = 88 – 9

JK = 79
