Answer:
1/216
Step-by-step explanation:
Easey
makes a right triangle with the building
hypotonuse is 13
and the height and base are the legs
we know that
for a right triangle with legs lgnth a and b and hypotonuse legnth c
c²=a²+b²
c=13
a=2
b=h
13²=2²+h²
169=4+h²
minus 4
165=h²
sqrt both sides
√165=h
aprox 12.8452=h
about 12.85ft
What is the expression ????

We are asked to solve for the angle AOB and we are given with the following values:
radius = 12 cm
length of AB = 15 cm
We can solve for angle AOC such as shown below:
sin AOC = opposite/hypotenuse
sin AOC = 7.5/12
∠AOC =38.68°
The angle subtended at the center of the circle is just twice of ∠AOC, then we have:
∠AOB = 38.68° x 2
∠AOB = 77.36°
The answer is 77° 21' 51.75".
