Question

the sine value of an angle of a triangle is 1/2, then the sum of other two angles is​

Answer 1

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 2

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.
