r nd the exact values of r and x given A 24 B 66 and y 3

nd the exact values of r and x given A = 24\", B = 66\", and y = 3. Do not enter the degree symbol in the entry area.

Solution

This is a right angle triangle.

A = 24^o

B = 66^o

y = 3

Then,

y/r = sinA ======> r = y/sinA = 3/sin24 = 7.38

and x/r = cosA ====> x = r*cosA = 7.38*cos24 = 6.74
