Answer:
37 degrees
Step-by-step explanation:
The tower and the shadow form legs of a right triangle. The angle of interest is the angle between a direct line from the shadow tip to the tower top, and the ground, adjacent to the shadow. The relevant trig relation is ...
Tan = Opposite/Adjacent
tan(angle of elevation) = (117 ft)/(158 ft)
The arctangent function is used to find the angle that has a given tangent.
angle of elevation = arctan(117/158) ≈ 36.52°
The angle of elevation is about 37°.
Answer:
a = -
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k ) = (105, 27 ) , thus
y = a(x - 105)² + 27
To find a substitute (109, 14 ) into the equation
14 = a(109 - 105)² + 27 ( subtract 27 from both sides )
- 13 = 16a ( divide both sides by 16 )
a = -

I am just cool like that trust me
Answer:
x=50° and y=45°
Step-by-step explanation:
x=QU(90°)-QP(40°)
x=50°
y=SU(90°)/2
y=45°
