Cos=(adjacent/hypotenuse)
So the answer will be cos(16/20) or cos(4/5) both will give u the same answer
I hope it helps
Answer:
6 is a answer
Step-by-step explanation:
if it is x 3+3 is equal to 6
if it is 10+10 is equal to 20
9) first option 10)last option
Step-by-step explanation:
We will use pythagoras' Theorem for this question

where c is the longest side (in this case, the diagonal)
a and b are the 2nd and 3rd longest side (interchangeable)
given a = 10.6, b = 16.8,

The next two numbers are 60 and 600. The pattern is to multiply the number by 10.
Hope that helped.
