There are 7 ducks swimming in a pond. If 3 have green wings and 4 have blue wings, what fraction of the ducks have green wings?
2 answers:
In the given question total number of ducks swimming in the pond is given as 7.
Out of these 7 ducks 3 have green wings and 4 have blue wings.
We need to find the fraction of ducks who have green wings.
The fraction of ducks having green wings can be found by dividing the number of ducks with green wings by the total number of ducks.
The number of green wings duck will be the numerator and the total number of ducks will be the denominator of the fraction.
Fraction of ducks which have green wings =

Answer:
= 115°
Step-by-step explanation:
Intersecting chord theorem,
"When two chords intersect inside a circle, then the measure of each angle is one half the sum of the measures of the arcs intercepted by the angle and its vertical angle."
By this theorem.
=
---------(1)
= 40°
= 100° + 60° + 30°
= 190°
By substituting these values in the expression (1)
=
= 115°
Therefore, = 115°
