Answer:
It is given that , In ΔW X Y, Y X is perpendicular to W Z. Also, y w= w z.
To Prove: ΔW X Y ≅ ΔZ Y X
Proof:
In Δ W X Y and Z Y X
Y X ⊥ W Z→→→→Given
Y W= Y Z→→(Given)
∠YWX=∠YZX→→As, opposite sides of a triangle are equal, so angle opposite to them are equal.
∠YXW=∠YXZ→→Each being 90°
So, ΔYXW≅ΔYXZ→→[AAS]
Also, YX is common sides between two triangles.
ΔYXW≅ΔYXZ→→[HL]
So,the two triangles can be proved congruent by either AAS, or HL.
The radius of the circle is a line from the center of the circle to its circumference
The radius of the circle with the same vertex as a center is 10.16 units
<h3>How to determine the radius</h3>From the question, we understand that:
- The adjacent sides of the triangle are 12 and
- The triangle has an angle of 60 degrees
Start by calculating the area of the triangle using:
So, we have:
This gives
The arc divides the triangle into two equal regions.
So, the area of the arc is:
Also, the area of the arc is:
So, we have:
Simplify
This gives
Divide both sides by 0.523
Take the square roots of both sides
Hence, the radius of the circle with the same vertex as a center is 10.16 units
