Answer: the measure of ∠X in parallelogram WZYX is 15°
Step-by-step explanation : In a parallelogram, opposite angles are equal. Therefore, if ∠W = 3m°, then ∠Z = 3m° as well. Given that ∠Z = (2m 5)°, we can set up the equation:
3m = 2m + 5
By solving this equation, we find:
m = 5
Now, we can find the measure of ∠X:
∠X = ∠Z = 3m = 3(5) = 15°
Therefore, the measure of ∠X in parallelogram WZYX is 15°
