Step-by-step explanation:
Answer:
need pic
Step-by-step explanation:
Answer:
cos(x) = square root 2 over 2; tan(x) = 1
Step-by-step explanation:

was, before it was rationalized,

Therefore,

The side opposite the reference angle measures 1, the hypotenuse measures square root 2. That makes the reference angle a 45 degree angle. From there we can determine that the side adjacent to the reference angle also has a measure of 1. Therefore,
and
since tangent is side opposite (1) over side adjacent (1),
tan(x) = 1
0.75 because 100cm = 1m so you just move the decimal to the right by 2
So do 81 divided by 4 we know that 80 divided by 4 is 20 so it would be 20 and some change
