Question

If the two angles of a triangle are 30 and 60 find the third angle

Answer 1

Answer:

sum of three angles =180

1 angle=30

2angle=60

let 3 angle be x

30+60+x=180

x=180-(30+60)

x= 180-90

x= 90

Answer 2

Given:

The two angles of a triangle are 30 and 60.

To Find:

The third angle of the triangle.

Solution:

The given problem can be solved using the concepts of triangles.

1. Consider a triangle with angles A, B, and C.  

2. According to the properties of triangles, the sum of all the internal angles of a triangle is 180 degrees.  

=> A + B + C = 180 degrees.

3. The given angles of the triangle are 30 and 60.

4. The third angle of the triangle can be calculated using the above formula,

=> 30 + 60 + C = 180,

=> C = 180 – (30 + 60),

=> C = 180 – (90),

=> C = 90.

5. The third angle of the triangle is 90 degrees.

Therefore, the third angle of the triangle is 90 degrees.
