Answer: 13m
Step-by-step explanation:
A^2+ B^2= C^2
5^2+ 12^2= c^2
169= C^2
then square root the 169 to get 13
Answer:
0.7048
Step-by-step explanation:
Use trap rule on the calc
all angles add up to 180, so add like terms and solve for x. plug x into C to find the angle C measure.
So we’re looking how many combinations we can make by selecting 5 items in a group of 17.
So we use n C r.
Where I the number of combinations of n objects taken r at a time.
So, 17 C 5
17! / (17-5)! 5! = 6188
(I hope this is correct)
Answer:
A
Step-by-step explanation:
note that these are the factors of a difference of squares
• a² - b² = (a + b)(a - b), hence
(x + 13)(x - 13)= x² - 13² = x² - 169 → A
