I have three questions on my homework in which I am stuck on. Thanks
for the help!
find all solutions of the equation in the interval [0,2pie). In cases
where a calculator is necessary, round the answers to two decimal
A 100 ft vertical antenna is on the roof of a building. From a point on
the ground, the angles of elevation to the top and the bottom of the
antenna are 51 degrees and 37 degrees, respectively. Find the height of
the building.
the length of the three sides of a triangle are denoted a, b, and c;
the angles opposite these sides are A,B, and C, respectively. In each
exercise, use the given information to find the required quantities.
c=4, a=2, B=90 degrees
