The bottom of a double rainbow is going over a tree that is 18 feet tall if you're standing 20 feet from the tree what is the angle of elevation to the bottom of the rainbow

The angle of elevation to the bottom of the rainbow is 42°

Explanation:

Given that the bottom of a double rainbow is going over a tree that is 18 feet tall and you're standing 20 feet from the tree.

We need to determine the angle of elevation to the bottom of the rainbow.

Let us use the trigonometric ratios to determine the angle of elevation.

Thus, we have,

where opp = 18 and adj = 20 and we need to determine the angle.

Substituting the values, we have,

Dividing the values, we have,

Taking on both sides of the equation, we get,

Thus, we get,

Rounding off to the nearest degree, we get,

Hence, the angle of elevation to the bottom of the rainbow is 42°

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 answer is somewhere there guys it really . there im just not gonna answer

step-by-step explanation:

but i'm guessing ur first option tho
