Answer:

  • tan B = 12/5
  • cos B = 5/13
  • sin B = 12/13

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you of the applicable ratios:

  Tan = Opposite/Adjacent   ⇒   tan B = CA/CB = 12/5

  Cos = Adjacent/Hypotenuse   ⇒   cos B = BC/BA = 5/13

  Sin = Opposite/Hypotenuse   ⇒   sin B = AC/AB = 12/13

Which expressions are equivalent to 16? Select each correct expression
photoshop1234 [79]

Answer: Choose 2 to the 4th power, 4 to the 2nd power, and 16 to the power of 1

Step-by-step explanation:

When working with exponents, whatever number is the corner of another number, multiply it by itself. For instance, if you have 2 to the 4th power, multiply 2x2x2x2 which is 16. Also there is 4 to the 2nd power which is 4x4 which is also 16. Lastly you have 16 to the power of 1 and anything multiplied by 1 stays the same.
