Question

the angles in the figure below form a straight angle. how could you write this expression with fewer terms? ( a + a + 100 = 180 )

Explanation:

Step1: Combine like terms

In the expression \(a + a+100 = 180\), since \(a+a = 2a\) (by the rule of combining like - terms in algebra: \(x + x=(1 + 1)x\)).

Answer:

\(2a+100 = 180\)
