Answer:
x = 3/4
Step-by-step explanation:
The lowest common denominator is 4(x + 2) so we multiply each side by this:
3 = 4x
x = 3/4.
Answer:
5/13
Step-by-step explanation:
Cosine ratio for an angle is defined as the ratio of Adjacent side to Hypotenuse.
We have to find the cosine ratio for angle F. The side adjacent to angle F is side GF and the hypotenuse of the triangle is side FH. The side opposite to the right angle is always the hypotenuse.
So, we can write:

Therefore, the cosine ratio of angle F is 5/13
