Robert is leaning a 30-foot ladder against the side of his house. The ladder makes a 40° angle with the ground. Standing at the top of the ladder, Robert can reach 3 feet above the point where the ladder rests against the wall. How high up on the wall can Robert paint? Draw an accurate diagram, and show all of the work for your solution. Round to one decimal place

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'.

the 3rd option is right
