Answer :
The value of y is 64°
Solution:
The image of the question is attached below.
Given two angles of a triangle.
One angle is 79°.
Other angle is 37°.
Let the unknown angle be y.
Triangle sum property:
Sum of all the angles of a triangle = 180°
⇒ y + 79° + 37° = 180°
⇒ y + 116° = 180°
⇒ y = 180° – 116°
⇒ y = 64°
Hence the value of y is 64°.
