Answer: the answer is 88.2 and your welcome!!
Tan x=31
x= tan^-1 (31)
x=88.2 degrees
16
-23, -20, -16, -10, -1, -1, 0, 0, 7, 10, 10, 11, 15, 16, 16, 17, 17, 17, 17, 19, 19, 22, 22, 24, 25, 25, 29, 35
$70
35 + 55 = 90
90 - 20 = 70
y = -13
y = 3x - 1 equation(i)
2x - y = 5 equation(ii)
now substitute the value of y in equation(ii)
2x - y = 5
2x - (3x -1) = 5
2x - 3x + 1 = 5
-x = 5 -1
-x = 4
x = -4
again substitute the value of x in equation (i)
y = 3x - 1
y = 3*-4 - 1
y = -12 - 1
