begin mathsize 16px style tan space straight theta subscript 1 equals straight h over straight x
rightwards double arrow straight theta subscript 1 equals tan to the power of negative 1 end exponent open parentheses straight h over straight x close parentheses
Now comma space height equals straight h plus 10 percent sign space of space straight h equals straight h plus straight h over 10 equals fraction numerator 11 straight h over denominator 10 end fraction
And comma space distance equals straight x plus 10 percent sign space of space straight x equals straight x plus straight x over 10 equals fraction numerator 11 straight x over denominator 10 end fraction
Now comma space tan space straight theta subscript 2 equals fraction numerator begin display style fraction numerator 11 straight h over denominator 10 end fraction end style over denominator begin display style fraction numerator 11 straight x over denominator 10 end fraction end style end fraction equals straight h over straight x
rightwards double arrow straight theta subscript 2 equals tan to the power of negative 1 end exponent open parentheses straight h over straight x close parentheses
Thus comma space straight theta subscript 1 equals straight theta subscript 2
rightwards double arrow Angle space of space elevation space remains space unchanged.
rightwards double arrow Given space statement space is space True. end style
