### Finding angle

Q An angle is $14^{0}$ more than its complementary. Then the measure of the angle is

a)$38^{0}$

b) $36^{0}$

c) $76^{0}$

d) $52^{0}$

Most of students have answered a). This is not correct.

Let the angle be x, then its complement will be 90 -x.
Now, the angle is 14 degree more than the complement,
form an equaion

x = 90 - x + 14
2x = 104
x= 52

(You can orally check...52 is 14 more than (90-52 = 38))
So, the correct answer is d).
