4 The people of Bridgetown wanted to build a bridge across a nearby river. Since they were poor swimmers, their
master Trigonomos agreed to measure the width of the river without actually crossing it. Trigonomos spotted a
tree across the river and marked the spot directly across from it. Then he walked to another point 15 m down
the river and found that the angle between side and the line connecting him to the tree was 76º.

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
