Question

Angle c and angle d are supplementary angles.
You're trying to find the measure of angle d. What value can you subtract from each side of the equation in order to have d remaining on the left?
c = 35ºbºaºeºdº
35+d

Answer 1

To isolate \( d \) on the left side of the equation \( 35 + d = 180 \), we need to subtract \( 35 \) from both sides of the equation.

Here's how you do it step-by-step:

1. Start with the equation:
\[
35 + d = 180
\]

2. Subtract \( 35 \) from both sides:
\[
35 + d - 35 = 180 - 35
\]

3. This simplifies to:
\[
d = 145
\]

So, you can subtract \( 35 \) from each side of the equation to isolate \( d \).
