Answer:

Step-by-step explanation:

This is 30°-60°-90° triangle, so the sides are in the ratio 1:√3:2

The side opposite the 30° angle is 10√3, so the side opposite the 60° angle is √3×10√3= 30, and the side opposite the 90° angle is 2×10√3 = 20√3.

Step-by-step explanation:

Divide by any number except 0 means the same as multiply by its inverse.

The inverse of $a$ is $\dfrac{1}{a}$

Therefore

$n\div(-1)=n\div\left(\dfrac{-1}{1}\right)=n\times\left(\dfrac{1}{-1}\right)=n\times(-1)=(-1)\times n=-1\times n$

Used the commutative property of multiplication: a × b = b × a

$\huge\boxed{-1\times n=n\div(-1)}$
