Question

In a right-angled triangle, if one angle is 60 then , what is the measure of its third angle?​

Answer 1

Answer:

30

Step-by-step explanation:

angle 1: 60

angle 2: 90

angle 3: unknown.

sum of all angles is 180 in a triangle.

180-90-60= 30

Answer 2

Answer:

30°

Step-by-step explanation:

We know that :—

• Angle 1 = 90° ( ∵ this is a right angled triangle )
• Angle 2 = 60° ( Given )
• The sum of all angles of a triangle is 180° .

With the above information , we can calculate the third side , which

= 180° - (90° + 60°)

= 180° - 150°

= 30°
