What you have presented is called a cyclic quadrilateral. A cyclic quadrilateral is a 4 sided figure whose angles (4 of them) all touch the circumference of a circle.
Here's what you want to know. Two angles that are opposite each other are supplementary (they add to 180 degrees)
Equation
x + 80 = 180 Subtract 80 from both sides.
Solution
x + 80 - 80 = 180 - 80 Combine
x = 100
Answer
x = 100
Answer:
(4,6)
Step-by-step explanation:
since they are negitave number and there being reflected across the y axis they will be positve
I would answer this but I am not sure
Answer:
3 months
Step-by-step explanation:
t^3 - 10t^2 + 33t - 36
3t^2 -20t + 33 = 0
(3t-11)(t-3) = 0
t = 3 or t=11/3
Answer:
The solutions are x=1 and x=-2/3
Step-by-step explanation:
we have

Group terms that contain the same variable, and move the constant to the opposite side of the equation

Factor the leading coefficient

Complete the square. Remember to balance the equation by adding the same constants to each side


Rewrite as perfect squares


square root both sides
