Answer:
The found angle D is:
D = 51.7°
Step-by-step explanation:
We have a right angle triangle with the right angle at F.
The given right angle triangle is shown in the diagram below.
EF = 95ft ⇒ Perpendicular of the triangle
FD = 75 ft ⇒ Base of the triangle
We have to find angle D.
Lets find angle D by using tan.
We know that
tan D = Perpendicular of the triangle / Base of the triangle
tan D = 95/75
D = tan⁻¹ (95/75)
D = 51.70983°
Rounding off the found angle to nearest 10th of a degree.
D = 51.7°

Answer:
Real values of x where x < -1
Step-by-step explanation:
Above the x-axis, the function is positive.
The function is decreasing when the gradient is negative.
The function has a positive
coefficient, therefore the vertex is a local minimum;
This means the gradients are negative before the vertex and positive after it;
To meet the conditions therefore, the function must be before the vertex and above the x-axis;
This will be anywhere before the x-intercept at x = -1;
Hence it is when x < -1.
