Question

what operation would you do to get the measure of angle 1 alone? m<1 + 152 = 180 subtract 152 add 152 rewatch skip submit

Explanation:

Step1: Isolate \(m\angle1\)

Given \(m\angle1 + 152=180\). To get \(m\angle1\) alone, we need to undo the addition of \(152\). According to the subtraction property of equality (if \(a + b=c\), then \(a=c - b\)), we subtract \(152\) from both sides of the equation.

Answer:

subtract 152
