Applying the tangent theorem and trigonometry ratio, the measure of angle A is: 19.5°.
<h3>What is the Tangent Theorem?</h3>
The tangent theorem states that if a line is tangent to a circle, the point at which the radius is drawn to the point of tangency is a right angle.
Thus, consider triangle AKO as a right triangle.
Therefore,
- angle A = reference angle
- Ok = 5 (opposite)
- AO = 15 (hypotenuse)
Using the trigonometry ratio, SOH, we have:
sin A = opp/hyp
sin A = 5/15
sin A = 0.3333
A = 19.5°
Therefore, applying the tangent theorem and trigonometry ratio, the measure of angle A is: 19.5°.

The sixteenth one which is
Answer:
Step-by-step explanation:
hello :
An = 10 -10/2^n
the first 4 terms are :
A1 = 10 -10/2^1 = 10-5
A1 = 5
A2 = 10 -10/2^2 = 10-10/4 = 10-5/2 = (20-5)/2
A2 = 15/2
A3 = 10 -10/2^3 = 10-10/8 =10- 5/4 = (40-5)/4
A3 = 35/4
A4 = 10 -10/2^4 = 10-10/16 = 10-5/8 = (80-5)/8
A4 = 75/8
Answer: There are 24 traffic lights on Berry Boulevard.
Step-by-step explanation:
Since we have given that
Total length of road = 
Number of roads on every 
= 2
So, According to unitary method,
In every , number of roads = 2
In every 1 mile, number of roads = 
So, in every 
the number of roads = 
Hence, there are 24 traffic lights on Berry Boulevard.
