<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

From the diagram:

63 + (15x - 3) = 180° (sum of angles on a straight line)

15x = 120

x = 8

m∠1 = 8x + 7 (opposite angles are equal)

m∠1 = 8(8) + 7 = 71°

The measure of m∠1 in the diagram attached is 71 degrees

The Sikhs are the ethnic groups who wanted a separate state of their own. The Sikhs are a follower of Sikhism. It is a monotheist religion in the Punjab region of India. During 1940s, the Sikhs worried that their community would be left without a homeland thus they push through the idea of Khalistan, seeing it as a small state that is a part of Punjab region.
