You need to find the angles and find the sides by using a^2+b^2=c^2
Answer:A complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x² = −1. Because no real number satisfies this equation, i is called an imaginary number.
Step-by-step explanation:
C; You know this because it asks for a dependent event. This means that a first event must occur that automatically changes the results for the following events. When you see dependent, look for without replacement.
Answer:
a = -4
b = 3
c = -10
d = -6
Step-by-step explanation:
Plug each value into the equation and solve.
Just do 12/6, 9/3, and 15/5
