Question

Two angles of a triangle measures 90° and 30°

. The measure of the third angle is ______ .​

Answer 1

Answer:

60°

Step-by-step explanation:

by using angle sum property Angle1 + Angle2+ Angle3 = 180°

We get,

90°+30°+ Angle3= 180°

Angle3 = 180° - 120°

Angle3 = 60°

Hope this will help you:)

Answer 2

60°

Step-by-step explanation:

becoz

<A=90° AND <B=30°

now

by angle sum property

<a+<b+<c=180°

90°+30°+<c=180°

<c=180-120

therefore <c=60°
