The correct answer is 82, because if you multiply 81 by 25 you get 2,025, you then subtract 72, add 97, and divide it all by 25

HELP WILL GIVE BRAINLIEST FOR ANSWER QUICKLY PLEASE HELP
Helen [10]

Answer:

We have sinθ = 12/13

The  method here is to figure out the value of θ

Using a calculator sin^(-1)(12/13) =67.38°

67.38° is in quadrant 1  so we must substract 67.38° from 180° wich is π

  • 180-67.38= 112.61° ⇒ θ= 112.61°

Now time to calculate cos2θ and cosθ using a calculator

  • cosθ = -5/13
  • cos2θ =  -0.7

The values we got make sense since θ is in quadrant 2 and 2θ in quadrant 3
