Step-by-step explanation:
sin 1/2 means 30° . Therefore one angle is 90° and other angle
= 180-90-30
=60°
Therefore sum of other two angles
=90° + 60°
=150°

Answer:90 and 45
Step-by-step explanation:
In a right angled triangle 1 angle is 90 other two are unknown.so sin x =1/2 is given . Therefore x =45° and the rest can be calculated by 180-90-45=45°.coz Sum of interior angles of a trinagle is 180.
