Answer:
Step-by-step explanation:
Remember that an inscribed angle is defined as an angle formed by two chords and whose vertex lies on the circle.
By definition, the measure of an inscribed angle is:
You know that:
Then, you need to substitute values and solve for "x":
Substituting the value of "x" into you get:

Answer:
The original length of each side of the equilateral triangle = x =15 inches
Step-by-step explanation:
Let Original length of side of equilateral triangle = x
If it is increased by 5 inches, the length will become = x+5
Since in equilateral triangle all the ides have same length so,
New Length of side 1 = x+5
New of side 2 = x+5
New Length of side 3 = x+5
Perimeter of triangle = 60 inches
We need to find the value of x
The formula used is:
Putting values in formula and finding x
So, the original length of each side of the equilateral triangle = x =15 inches
