Question

please friends answer this as fast as possible........

two angles are complementary. The larger angle is 3 degree less than twice the measure of smaller angle. find the measure of each angle ?

Answer 1

let the larger angle be x and smaller angle be y
larger angle=2y-3
according to the given condition,
x+y=90
2y-3+y=90      ( since x=2y-3)
3y-3=90
3y=93
y=93/3
y=31
 so smaller angle y = 31degrees
       larger angle = 2*31-3=59
 so 59+31=91

Answer 2

Let the first angle be x°

So second angle = (2x - 3)°

So, since they are complementary -

x + 2x - 3° = 90°
3x = 93°
x = 31°

So, fist angle = x = 31°
Second angle = (2x - 3)° = 59°
