Which system of equations represents the matrix shown below?
3 6 -181
1-2 3 04
[4 5 4
3x+6y +z = 8
a. 2x+3y +z = 4
4x+5y + 4z = -2
3x+6y +z = 8
b. 2x+3y + 2z - 4
4x + 5y + 4z = 2
3x+6y - z = 8
c. -2x + 3y - 4
4x+5y + 4z = -2
3x+6y-z 8
d. -2x+3y + z = 4
4x+5y + 4z = -2

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130
