Answer:
He did the complete opposite of what he needed to do
Step-by-step explanation:
The error is that when you need to find x - intercept, you need to replace the value of y with zero, not the y value.
Cause otherwise, what he did here is to find the y - intercept
If you have any questions about the way I solved it, don't hesitate to ask me in the comments below :)
The first one is D because c represents the x and b represents the y. For the second one:
38(2) = 76
180-76 (this is the sum of the unknown measures)
104/2 (finds the measure of each angle)
52
I am unsure of the final one though.
Hope this helps!
Answer:
10√3m
Step-by-step explanation:
Given :-
- Angle of elevation = 60°
- Distance between man and pole = 60°
We need to find the height of the pole . We are given here base. Therefore using ratio of tan ,
=> tan 60° = p/b
=> √3 = h / 10 m
=> h = 10 m× √3
=> h = 10√3 m
Dist. travelled for the first 2 days
= 22 + 28
= 50
Dist. travelled for the remaining 83 days
= 1378 - 50
= 1328
Dist. travelled for EACH of the 83 days
= 1328 ÷ 83
= 16
