Answer:
value of a = 6.93 m
hence , (b.)
Step-by-step explanation:
the given triangle is a right angled triangle, so
by using trigonometry.
=》
and we know,
=》
so, by above values of tan ( a ) we get,
=》
=》
=》
=》
=
=》
hence, a = 6.93 m

Answer:
Angle made by ramp with ground is ≈
Step-by-step explanation:
Diagram of given scenario is shown below.
Given that,
Horizontal Distance of Skateboard ramp is ft.
Height of Skateboard ramp is ft.
From figure,
It is forming a Right angle triangle .
In ,
and
.
Clearly see that we need to find measure of angle .
Using Trigonometric ratio:
So,
Then
Therefore, Angle made by ramp with ground is ≈
