What is 10^-3 in math
Alborosie
It is 1/1000 or 1/10∧-3
that is because whenever there is a negative exponent put it as the denominator and the numerator by default, if there isn't any, should be one. 
so put it under and then figure it out

What is the area of a triangle whose side is 17 meters long​
Lunna [17]

Answer:

125.141

Step-by-step explanation:

Assuming that this is an equilateral triangle, I am going to divide this triangle in half to get a right triangle.

17 is our hypotenuse

17/2 = 8.5, this is one of our legs

The other leg is our height, which we will find.

We use Pythagoras Theorem to find the height/leg: a^{2} +b^{2} =c^{2}

17^{2} -8.5^{2} = 216.75

\sqrt{216.75} = 14.72243186

Now, we use another formula to find the area of the triangle: \frac{Base*Height}{2}

14.72243186 × 17 = 250.2813416

250.2813416 ÷ 2 = <u>125.1406708</u>
