♡ Given:
♡ To find:
♡ Answer:
♡ Solution:
We know that the sum of angles in a straight line is 180°,
6y + 2y + y = 180°
(Sum of angles in a straight line is 180°)
9y = 180°
♡Verification:
The value of y = 20°
So, putting the value of y in 6y + 2y + y = 180°, we get:
6(20°) + 2(20°) + 20°
= 120° + 40° + 20°
= 180°
LHS = RHS,
Hence Verified too!
♡ Concepts Used:
♡ Extra - Information:
➠ The sum of angles in a linear pair is 180°
➠ In a supplementary pair of angles, the sum of both angles is 180°.
➠ The sum of complementary angles is 90°
➠ Vertically Opposite angles are equal.
➠ 90° angle is known as 'right angle'.
