Suppose there is a 1.7°F drop in temperature for every thousand feet that an airplane climbs into the sky. If the temperature on the ground is 57.8°F, what will be the temperature when the plane reaches an altitude of 2,000 ft

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'.

what are your options?

step-by-step explanation:

the answer would be 9 because if it is perpendicular to the green line. the red lines slope is the opposite or reciprocal of the slope of the green line.
