Answer:

Step-by-step explanation:
The picture of the question in the attached figure
we know that
A <u><em>circumscribed angle</em></u> is the angle made by two intersecting tangent lines to a circle
so
In this problem
BC and CD are tangents to the circle
BC=CD ----> by the Two Tangent Theorem
That means
Triangle ABC and Triangle ADC are congruent
so

Find the measure of angle BAC
In the right triangle ABC

substitute given value


Find the measure of angle BAD


Find the measure of minor arc BD
we know that
-----> by central angle
therefore

Answer:
Step-by-step explanation:

Length of tower:-
Therefore, the tower is 93.6ft tall.
<u>-------------------------------------------</u>
The question is an illustration of right-angled triangles
The approximated value of x is 33.5 degrees
The given parameters are:



To determine the measure of angle x, we simply make use of the following sine ratio.

So, we have:


Take arc sine of both sides

This gives

Hence, the approximated value of x is 33.5 degrees
