Question

one of the acute angle of a right triangle is 63 . find the other acute angle

Answer 1

let the other acute angle be x°
so
90°+63°+x°=180°
(angle sum property of a triangle)
153°+x°=180°
x°=180°-153°=27°

thus the other acute angle is 27°

Answer 2

let the other acute angle be x

there fore

x + 90 + 63 = 180

x + 153 = 180

x = 27
