Answer:

It is a right triangle.

Step-by-step explanation:

A right triangle is a triangle with at least one angle with 90 degrees.

We know that every triangle has 180 degrees. The other unknown angle is 180 - (30+60) = 180 - 90 = 90. That means that the other angle is 90 degrees. Therefore, it is a right triangle

We also know that in this triangle, that the square of one side plus the square of another is side is equal to the square of the hypotenuse of the triangle. (According to Pythagorean theorem)

The answer is 130°
Because it is a circle, the angles have to all add up to 360°. So if you add up the two known angles, and subtract that sum from 360, you will get 130°

Anthony borrowed $18,800 at 6% simple interest for 4 months. Determine the amount of interest.
anygoal [31]
First, converting R percent to r a decimal
r = R/100 = 6%/100 = 0.06 per year,
putting time into years for simplicity,
4 months ÷ 12 months/year = 0.333333 years,
then, solving our equation

I = $ 376.00

I = 18800 × 0.06 × 0.333333 = 375.999624
I = $ 376.00

The simple interest accumulated
on a principal of $ 18,800.00
at a rate of 6% per year
for 0.333333 years (4 months) is $ 376.00.

What is the distance between -25 and 15 on a number line?
storchak [24]
Well if you have one that’s negative and one that’s positive, I’m guessing that you would add them. So 25+15 is 40. Also the distance will always be positive because it can only be that way. Otherwise we might have a singularly on our hands, heheh... So the distance is 40 between these 2 points.
