An inscribed angle has a measure of 48°. Determine the measure of the intercepted arc.
BabaBlast [244]
An inscribed angle has a measure of 1/2 of the intercepting arc.  Since our angle is 48°, we can set up the equation 48=\frac{1}{2}x to represent this.  Divide both sides by 1/2:
\frac{48}{\frac{1}{2}}=\frac{\frac{1}{2}x}{\frac{1}{2}}
\\ 48 \div \frac{1}{2} = x
\\ \frac{48}{1} \div \frac{1}{2} = x
\\ \frac{48}{1}*\frac{2}{1} = x
\\ \frac{96}{1}=x
\\ 96=x
The measure of the intercepted arc is 96°.

Mary is flying a kite and has let out 50 yards of kite string. Mary’s kite is directly above Erika.
ch4aika [34]

The distance of Erika from kite directly is 35.71 yards

Step-by-step explanation:

Considering the given situation as a right triangle with string as hypotenuse and the distance between both girls as base

So,

h = 50\ yards\\b = 35\ yards

As the triangle is a right triangle, we can use pythagoras theorem to solve this problem.

h^2 = b^2 + p^2\\p^2 = h^2 - b^2\\p^2 = (50)^2 - (35)^2\\p^2 = 2500-1225\\p^2 = 1275\\\sqrt{p^2} = \sqrt{1275}\\p = 35.707\ yards

Rounding off to nearest hundredth

=> 35.71 yards

Hence,

The distance of Erika from kite directly is 35.71 yards
