Question

A right angles triangle has an angle measure 60° find the other angle.​

Answer 1

Answer:

30°

Step-by-step explanation:

right angle= 90°

lets take other angle as X

X+60°= 90°

X= 90°-60°

=30°

Answer 2

Answer:

30°

Step-by-step explanation:

In every triangle, the summation of all the inner angles is 180°

In right-angled triangles, there is always a right angle.

The value of a right angle is 90°

Suppose, the angles of the following triangle are,

   a = 90° [The Right Angle]

   b = 60° [Given in the question]

   c = ? [It has to be detirmined]

Now,

    a + b + c = 180° [Summation of every angles]

Or, 90° + 60° + c = 180° [The values of a and b is inserted]

Or, 150° + c = 180°

Or, c = 180° - 150°

   ∴ c = 30°

Ans: The value of the needed angle is 30°

Hope you understand the process...
