Wouldn't all the angles equal 180? We've been trying to learn these but I think so. Subtract both numbers by 180 and it should be the answer. Sorry if it's wrong but I'm not sure. I kinda hope this helps you any

Answer:
3 / 13
Step-by-step explanation:
Hello!
There are 52 cards in a deck with half being red and half being black. The question ask for when a black card is drawn so we divide the total by 2
52/ 2 = 26
There are 6 black face cards in a deck so to get the probability one will be drawn we put how many there are over the total amount
6/26 we can simplify this
3 / 13
The answer is 3 / 13
Hope this helps!
Answer:
(2x + 11)(2x - 11)
Step-by-step explanation:
4x² - 121
rewrite the expression in the form of (a)² - (b)²:
(2x)² - (11)²
difference of squares a²-b²=(a+b)(a-b):
(2x + 11)(2x - 11)
