Solve each system of equation<br> Y=-3x+5 <br> 5x-4y=-3
____ [38]
Y = -3x + 5
5x - 4y = -3

   5x - 4(-3x + 5) = -3
5x + 4(3x) - 4(5) = -3
     5x + 12x - 20 = -3
             17x - 20 = -3
                   + 20  + 20
                    17x = 17
                     17     17
                        x = 1
                        y = -3x + 5
                        y = -3(1) + 5
                        y = -3 + 5
                        y = 2
                  (x, y) = (1, 2)

Step-by-step explanation:

Data

length = 18 ft

distance bottom to is 13 ft

x = angle = ?

cos Ф = opposite side / hypotenuse  

Process

cos Ф = 13 ft / 18 ft                   substitution

cos Ф = 0.72                            simplify

Ф = cos⁻¹ (0.72)

Ф = 43.95°                                result
