Question

Identify whether the given triplet can be the angles of a triangle: 30,142,20

Answer 1

Answer:

No because the sum of all these angles is not 180

Answer 2

Required Answer:-

GIVEN

• Triplets- 30,142,20

TO FIND

• Whether the given triplets can be the angles of a triangle.

ANALYSIS

Here, we need to find whether these three given angles {30,142,20} can be angles of the triangle. As we all know that sum of all three angles of triangle is 180 degrees we will find out our answer.

SOLUTION

$\implies\sf 30^\circ+142^\circ+20^\circ = 180^\circ$

$\implies\sf 142^\circ+50^\circ = 180^\circ$

$\implies\sf 192^\circ \cancel {=} 180^\circ$

FINAL ANSWER

As we know, the sum is not equal to 180 degrees, these triplets are not angles of a triangle.
