Answer:

60°, 60°, and 60°

Step-by-step explanation:

A triangle with three equal side lengths is called and equilateral triangle. If the sides of an equilateral triangle are all the same, then the angles will be as well.

All triangles have a sum of 180°. This means that if you add up the the measures off all three angles, it will be 180°.

So, for equilateral triangles, you can divide the total number of degrees, (180), by the number of sides, (3).

180/3 = 60

So, each angle on an equilateral triangle has a measure of 60°

Ratling [72]

Answer:

Area of the rectangular pen is: $18 \,x-x^2$

Step-by-step explanation:

We need to specify that the perimeter of the rectangular area of side x adds to the amount of fence Pablo has (36 feet). Recall as well that the opposite sides of a rectangle are equal, so if there is a side of length x, there must be another one of this size as well (a total of 2 x in the perimeter),let's assume that the perpendicular sides to x are of length y, then:

Perimeter= 2 x + 2 y = 36

so, 2 (x+y) = 36 then (x+y) = 18

and therefore the side y should be:

y = 18 - x

Now we can write the formula for representing the area of the rectangle (product of both quantities: x * y

$Area=x\,*\,y = x\,(18-x) =18 \,x-x^2$

Answer:

∠ D = 127°

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ D is an exterior angle of the triangle , then

∠ D = 85° + 42° = 127°

You will receive $15000 I’m two years when you graduate. You plan to invest this at an annual interest rate of 6.5 percent. How

Crank

You will have $24 824.94 eight years from now.

The formula for the future value (FV) of her investment is

FV =C(1 + r)^n

where C = her initial cash

r = the interest rate

n = the number of years

FV = $15 000(1.065)^8 = $24 824.94
