Question

if the measure of one angle of a right angle triangle is 48, find the other two angles

Answer 1

Given that one of right angled triangle is 48 degree.
We know that in right angled triangle one angle is equal to 90 degree. Then,
first angle = 90 degree , second angle = 48 degree and third angle = ?
We know that the sum of three angles of a triangle is always equal to 180 degree.
Therefore, first angle + second angle + third angle = 180 degree
90+48+third angle=180
138+third angle=180
third angle=180-138=42 degree.

Answer 2

sum of all angles in a triangle = 180°
90° + 48° + x = 180°
138° + x = 180°
x = 180° - 138°
x = 42°
