Answer:
x = 7
z = 7
v° = 60°
w° = 60°
y° = 60°
Step-by-step explanation:
The tick marks on the sides of the given triangle indicate that the side lengths are equal. Therefore, this is an equilateral triangle.
In an equilateral triangle, all three sides are equal in length, and all three angles are equal in measure.
Given that one of the side lengths of the equilateral triangle measures 7 units, the other two sides also measure 7 units:
The interior angles of a triangle sum to 180°. Therefore, since the interior angles of an equilateral triangle are equal in measure, each angle must be one-third of 180°. One-third of 180° is 60°, so:
