# Explanation:
## Step1: Recall supplementary - angle property
Supplementary angles sum to 180°. So, $m\angle ABC + m\angle ABD=180^{\circ}$.
## Step2: Substitute angle - measures
Substitute $m\angle ABC=(3m - 15)^{\circ}$ and $m\angle ABD=(5m + 50)^{\circ}$ into the equation: $(3m - 15)+(5m + 50)=180$.
## Step3: Simplify the left - hand side
Combine like terms: $3m+5m-15 + 50=180$, which simplifies to $8m+35 = 180$.
## Step4: Isolate the variable term
Subtract 35 from both sides: $8m=180 - 35$, so $8m=145$.
## Step5: Solve for $m$
Divide both sides by 8: $m=\frac{145}{8}=18.125$. But there seems to be an error above. Let's correct step 2.
## Step2 (corrected):
$(3m-15)+(5m + 50)=180$
$3m-15+5m + 50=180$
$8m+35 = 180$
Subtract 35 from both sides: $8m=180 - 35=145$
$m=\frac{145}{8}$ is wrong. It should be:
$(3m - 15)+(5m+50)=180$
$3m-15 + 5m+50=180$
$8m + 35=180$
$8m=180 - 35=145$ (wrong).
The correct equation:
$(3m-15)+(5m + 50)=180$
$3m+5m-15 + 50=180$
$8m+35 = 180$
$8m=180 - 35=145$ (error).
The correct:
$(3m-15)+(5m + 50)=180$
$3m+5m-15+50 = 180$
$8m + 35=180$
$8m=180-35$

$8m=145$ (mistake).
