Answer:   C. (-4, -2)

<u>Step-by-step explanation:</u>

First, eliminate one of the variables and solve for the remaining variable:

2x - 5y = 2      →    3(2x - 5y = 2)      →     6x - 15y = 6

3x + 2y = -16   →  -2(3x + 2y = -16)    →  <u> -6x - 4y = 32</u>

                                                                     -19y = 38

                                                                         y = -2


Next, replace "y" with -2 into either of the original equations to solve for x:

2x - 5y = 2

2x - 5(-2) = 2

2x + 10 = 2

2x         = -8

 x          = -4

                                       x = -4,  y = -2

<u>Check:</u>

Plug in the x- and y-values into the other original equation:

3x + 2y = -16

3(-4) + 2(-2) = -16

-12  +  -4     = -16

      -16         = -16   \checkmark

jek_recluse [69]

Answer:

A) 38.62 ft

B) 92.27 ft

C) 32.59 ft

Step-by-step explanation:

A) tan10= x/185

X= 32.62 + 6ft= 38.62ft

B) tan25= x/185

X= 86.27 + 6ft= 92.27ft

C) 92.27 - 6ft= 86.27

86.27+ 32=118.27

use inverse of tan tan-1= 118.27/185 in which you get 32.59ft
