Answer:
6.86 to 2DP.
Step-by-step explanation:
7/12 = 4/DC
Cross multiply:
7DC = 4*12
DC = 48/7
= 6.857.
1) The angle of depression is complementary to up angle of the right triangle:
=> Angle of depression = 90° - up angle
=> up angle = 90° - angle of depression
2) The angle of depression is equal to the bottom angle of the right triangle.
=> bottom angle = angle of depression.

Step-by-step explanation:
Answer:
no you're not wrong go with your gut
Step-by-step explanation:
The largest prime that needs to be checked for factors of a number n is floor(sqrt(n)), or |sqrt(n)| in some notations, meaning the largest integer that does not exceed sqrt(n).
For example, if checking 169, whose squre-root is 13. There will be NO prime factors below 13 (1 is not a prime). So check for all prime factors up to and including the largest prime equal to or less than sqrt(n).
