independent practice
answer each question below. m
find the value of x.

if the measure of ∠adc is 50°, then what is the measure of ∠bdc?

Explanation:

Step1: Identify angle relationship

The largest angle is the sum of the two smaller angles, so $x + 84 = 112$.

Step2: Solve for x

Subtract 84 from both sides.
$x = 112 - 84$

Answer:

$28$
