The measure of angle X in triangle VWX is 40°
In triangle VWX, if WX is congruent to VW (denoted as WX ≅ VW), and angle V (m/V) is given as 40°, we can use the properties of isosceles triangles.
In an isosceles triangle, if two sides are congruent, then the angles opposite those sides are also congruent.
So, in triangle VWX:
- m/V = m/X (angle opposite the congruent sides WX and VW)
- m/V = 40°
Therefore, m/X = 40°.
So, the measure of angle X (m/X) in triangle VWX is 40°.
