Answer:

Step-by-step explanation:

I really hope that solving a few trig questions can forestall death. That would be a really easy way to get rid of the C 19 restrictions and a myriad other diseases. BETTER LIFE THROUGH MATH will be our motto.

11) tan45 = x/13     x = 13

   cos45 = 13/y     y = 13√2

12) sin30 = 4/x      x = 8

     tan30 = 4/y     y = 4√3

13) sin60 = 21/x    x = 21(2/√3) = 42/√3

    y = xcos60 = (42/√3)(1/2) = 21/√3

14) cos45 = x/22   x = 22/√2

     sin45 = y/22   y = 22/√2

15) Height = 24sin30 = 12

cos 45 = 12/x   x = 12/√2

tan45 = y/12      y = 12

cos30 = z/24    z = 24(√(3)/2) = 12/√3
