Question

if m∠vwy = 51° and m∠vwx = 81°, what is the m∠ywx?

Explanation:

Step1: Identify angle - relationship

We know that $\angle VWX=\angle VWY + \angle YWX$.

Step2: Solve for $\angle YWX$

$\angle YWX=\angle VWX-\angle VWY$.
Substitute $\angle VWY = 51^{\circ}$ and $\angle VWX = 81^{\circ}$ into the formula: $\angle YWX=81^{\circ}- 51^{\circ}$.

Step3: Calculate the result

$81 - 51=30$. So, $\angle YWX = 30^{\circ}$.

Answer:

$30^{\circ}$
