Question

Find the value of x.

  1. 35°
  2. 27°
  3. 16.8°
  4. 16°

The correct answer is: 16.8°


    in the given question triangle is a right angle triangle
    so the sum of two angle expect right angle = 90 to the power of o
    so2 x to the power of o space plus space 3 x to the power of o space plus space 6 to the power of o space equals space 90 to the power of o
5 x to the power of o space equals space 90 to the power of o space minus space 6 to the power of o
x to the power of o space equals space 84 to the power of o over 5 to the power of o
x to the power of o space end exponent equals space 16.8 to the power of o space a n s w e r
    so the choice 3 is the correct answer
