the angle of elevation to the top of the egyptian pyramid cheops is 36.4 degrees measured from a point 350 feet from the base of the pyramid. the angle of elevation of a face of the pyramid is 51.9 degrees. find the height of the cheops

Now, let's start with the Guitarists:  they are 5/8 of the 64 musicians, that is

64*

now, some number to 40 (total number of the guitarists) has the ratio of 1:4
ratios remain equivalent if we multiply both numbers by the same number.

so the ratio of 1:4 is equivalent to 10:40.

this means that there are 10 Jazz solos guitarists.

And how many classical solo guitarists were there? the rest! 40-10=30

so the answer is 30
