4:30 PM! Because you have to add up all the time he spent doing these activities which is 3 hours and what time is three hours before 7:30? The answer is 4:30! Hope this helps!
Answer:

Step-by-step explanation:
Given

Required
Use the expression to prove a trigonometry identity
The given expression is not complete until it is written as:

Going by the Pythagoras theorem, we can assume the following.
- a = Opposite
- b = Adjacent
- r = Hypothenuse
So, we have:


Having said that:
The expression can be further simplified as:

Substitute values for sin and cos
becomes

The answer is 8/12 because you find a common denominator which is 12 so if you multiply 4×3 on the bottom you do it to the top which gives you 3 so 11-3 is 8. 11/12 - 3/12
To find the slope between the points, you would go through this process
(-1-6)/(4-0)
And we get
(-7)/4
Aka
-(7/4) which is our slope
X= 48
this is found by simplifying both sides of the equation , then isolating the variable<span />
