Answer:
A and D
Step-by-step explanation:
Since tangent is opposite/adjacent,
Tan 40 in this case would be x/3.8 (i used x because we don't know what the value is)
So, you set it up as an algebra problem
Tan40 = x/3.8
Multiply both sides by 3.8
3.8tan40 = x, Option A
And then, angle E is 50 degrees
So tan 50 = 3.8/x
Multiply both sides by x
tan50x = 3.8
Divide both sides by tan50
x= 3.8/tan50
So, A and D are both correct
Answer:
C. 2
Step-by-step explanation:
To solve slope, the formula is 
. 9-3 is 6 and 5-2 is 3. So simplify 6/3 to 2.
Hope it's correct!

Answer:
Option A. is the correct option.
Step-by-step explanation:
If a number is divisible by 5 it is not necessary that the number will be divisible by 10.
For example: 25 is the number divisible by 5 but not divisible by 10.
Or in other words a number divisible by 5 should be even to be divisible by 10.
So for the conditional statement : A number is divisible by 10 if and only if it is divisible by 5 will be false because any one out of these two statements is false. We know biconditional is true only when both the statements are true or false means both the statements should have same truth value.
Therefore Option A. is the correct option.
