Find the measure of the missing angle to the nearest degree
GarryVolchara [31]

Answer:

  22°

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you ...

  Tan = Opposite/Adjacent

The side opposite the marked angle is 10; the side adjacent is 25, so we have ...

  tan(?) = 10/25 = 0.4

  ? = arctan(0.4) ≈ 21.801° ≈ 22° . . . . . . using the inverse tangent function

The measure of the indicated angle is about 22°.
