Answer: D
Explanation: Apply the pythagorean theorem (a^2 + b^2 = c^2) to get 11^2 + b^2 = 18^2. From that you can solve for b and you get the square root of 203.
Hope this helped! :)
Here is your function graphed
Answer:
All angles in a quadrilateral = 360°
b =?
b = 360 - (128 + 61 + 57)
b = 360 - 246
b = <u>1</u><u>1</u><u>4</u><u>°</u>
This is the image the points form, if you know your quadrilaterals, this should make it easier to picture and label. Need any further explanation?
