Answer:
13.9
Step-by-step explanation:
Use Pythagorean Theorem:
Both of the lengths given are the legs,
13.5^2 + 3.2^2 = c^2
182.25 + 10.24 = c^2
192.49 = c^2
13.87 = c
The arithmetic sequence with the given condition is determined recursively by
So we have
and so on with the general pattern
This means the 72nd term in the sequence is
so the answer is B.
The awnser is 148 You just need to add the two to get the original price
Answer:
3x-20=-6.6 degrees, 7x+10=1.4 degrees
Step-by-step explanation:
You solve each equate separately. So take the equation (3x-20) and solve for x first in that one. so you divide 3 by -20 to get -6.66 degrees for your first angle. Then you solve the other equation. (7x+10) divide 7 by 10 to get the angle measurement. Which would be 1.4 degrees.
