Use Pythagorean theorem:
9i-j = sqrt (9^2 - 1^2) = sqrt(81-1) = sqrt80
now divide both terms in V by that:
u = 9/sqrt(80)i - 1/sqrt(80)j

Answer:
100 cm
Step-by-step explanation:
Given:
AC = BC
AC = 40
2AB=AC
Simplify:
BC = 40
Simplify:
2AB = 40
Algebra:
AB = 20
Here's the sides:
AB = 20
AC = 40
BC = 40
Add all of them together:
100
A. Hydrogen and oxygen are classified as elements.
Explanation: they are from the periodic table (which is a table of elements) and it wouldn’t make sense for them to be minerals, energy or organisms. They aren’t living things.
Answer:
Two angles are called complementary if their measures add to 90 degrees, and called supplementary if their measures add to 180 degrees. ... For example, a 50-degree angle and a 40-degree angle are complementary; a 60-degree angle and a 120-degree angle are supplementary
