Answer:
There is no result.
Step-by-step explanation:
This question does not have an answer, as you would need to plug in an x value to get any sort of answer.
Answer with Step-by-step explanation:
We are given that:
tanA = 0.45
tanA= 
= 
⇒
=0.45
⇒
=
⇒
=
⇒ AC= 20
Hence, by pythagoras theorem
AB²=AC²+BC²
AB²=20²+9²
AB²=481
⇒ AB=21.9 units
Hence, the approximate length of AB is:
22 units
Answer:
84.1%
Step-by-step explanation:
Add up 0.1, 2.2, 13.6, 34.1, and 34.1 and you get that number. this is because that is the numbers in each column and you add those because they are below 79 mark.
Answer:
10x-2y
Step-by-step explanation:
distribute for both of them then multiply both answers by 2 and add them
2(x+y)= (2x+2y) x2= 4x+4y
3(x-y)= (3x-3y) x2= 6x-6y
4x+4y+6x-6x
10x-2y
