Answer:
52°
Step-by-step explanation:
The measure of angle between the ladder and the ground is given as:
Sum of angles in a triangle
38° + x° + 90° = 180
128°+X° = 180°
X° = 180-128
X= 52°
Hence the angle x = 52°

Step-by-step explanation:
Answer:
d = 3
Step-by-step explanation:
Expand the right side and compare the coefficients of like terms
x² + 6x + c = x² + 2dx + d²
For the 2 sides to be equal then coefficients of like terms must be equal
compare coefficients of x- terms, then
2d = 6 ⇒ d = 3
