Answer: (The sides are therefore chords in the circle!) This conjecture give a relation between the opposite angles of such a quadrilateral. It says that these opposite angles are in fact supplements for each other. In other words, the sum of their measures is 180 degrees.
Answer:
i predict the 150 will have defects
Step-by-step explanation:
you do 280 divided by 4 which gives you 70
then 10,500 divided by 70 which gives you
Given:

Required:
We need to find the solution by Vièta's theorem.
Explanation:
Compare 1st equation with

we get

Vièta's theorem is


now solve this equation and we get

because addition of 1 and 2 is 3 and multiplication is 2
Now for 2nd equation

apply Vièta's theorem

by this

because addition of 3 and -5 is -2 and multiplication is -15
Answer:1
Step-by-step explanation:
A:15
B: -15
C: 9
I hope this helps
