Answer:
x = -4, -2
Step-by-step explanation:
-x² - 6x - 8 = 0
x² + 6x + 8 = 0
x² + 4x + 2x + 8 = 0
x(x + 4) + 2(x + 4) = 0
(x + 4)(x + 2) = 0
x=-4 x=-2
Set this equal to zero to find the solutions
0=- x^2-6x-8
Divide by -1
0/-1 = x^2 +6x+8
0 = x^2 +6x+8
Factor
What 2 numbers multiply to 8 and add to 6
4*2 = 8
4+2 = 6
0 = (x+4)(x+2)
Using the zero product property
x+4 = 0 x+2 =0

p= 27
b= 48
now finding the value of x,
tanx°= p/b
=27/48
=0.56
now,
x°= tan-¹ 0.56
= 29.24

5/3 = 3/3 * 2/3
3/3 = 1
So the answer is 1
