Is -4 greater then or less then -5
2 answers:
Answer: -4 is greater than -5
To understand why, let’s look at a number line.
In the image provided, we can see that -4 is 4 units away from zero and -5 is 5 units away from zero. It may be confusing at first, but negative numbers that are closer to zero are going to be greater than numbers that are not as close to zero.
Number lines are a great tool especially when introducing integers because they help you visualize what’s going on.

Answer:
3/5
Step-by-step explanation:
sin theta=opposite/hypotenuse
4/5=opposite/hypotenuse
therefore opposite=4 and hypotenuse=5
for adjacent
using pythagoras theorem
a^2+b^2=c^2
opposite^2 + adjacent^2 =hypotenuse^2
4^2 + adjacent^2 =5^2
16 + adjacent^2 =25
adjacent^2 =25-16
adjacent =
adjacent=3
cos theta=adjacent/hypotenuse
=3/5
therefore the value of cos theta is 3/5
