Geometry right triangle trig heelppp !

3. x= 20.1

4. x = 22.0

Step-by-step explanation:

SohCahToa. S= sin, C= cos, T=tan.

o = Opposite (the side on the other side of the given angle, also referred to as theta.)

h = Hypotenuse (the side on the other side of the right angle, represented as the square thing.)

a = Adjacent (side next to the given angle.)

3. We have opposite = x, adjacent = 24. We can use tan (Toa.)

  tan(40º) = x/24         Multiply both sides times 24.

  x = 24*tan(40º)         Put into calculator

  x = 20.1

4. We have adjacent = 12, hypotenuse = x. We can use cos (Cah.)

  cos(57º) = 12/x         Multiply both sides by x

  x*cos(57º) = 12         Divide by cos(57º)

  x = 12/cos(57º)         Put into calculator

  x = 22.0

use formula for the circle a=3.14
