Question

Let ABC be a triangle such thestraight A with _ below equals 45 to the power of ring operator comma straight B with _ below equals 75 to the power of ring operator ,then a plus c square root of 2 equal to

  1. 0    
  2. 2b    
  3. b    
  4. -b    

The correct answer is: 2b


    To find the value of  a plus c square root of 2 .
    Given, ABC is a triangle such that straight A with _ below equals 45 to the power of ring operator comma straight B with _ below equals 75 to the power of ring operator
    fraction numerator a over denominator sin space 45 end fraction equals fraction numerator c over denominator sin space 60 end fraction equals fraction numerator b over denominator sin space 75 end fraction equals d

a equals fraction numerator d over denominator square root of 2 end fraction comma space c equals fraction numerator square root of 3 d over denominator 2 end fraction comma space b equals fraction numerator square root of 3 plus 1 over denominator square root of 2 square root of 2 end root end fraction d

a plus c square root of 2 equals fraction numerator square root of 3 plus 1 over denominator square root of 2 end fraction d equals 2 b

    Therefore,a plus c square root of 2=2b
