Answer:
112 degrees.
Step-by-step explanation:
- as we know that the three set of forces will form a triangle, by using cosine rule, we can find the required angle.
- follow the diagram in the attachment.
- by cosine rule for
,
2*10*8*cos
= 
now, dividing both sides by 2*10*8,
cos
= -61/160
= 112.4 degrees = 112 ( appox) ( use calculator for this cos inverse function)

Note: When finding the percent of a number multiply the percent times the number.
Answer:
The length of DF must be between 21 and 53.
Step-by-step explanation:
In a triangle, the length of two sides added together must exceed the length of the 3rd side. So, since EF is the shortest of the two givens, we know that EF + DF must be greater than DE. So we can plug in these numbers to find the minimum.
EF + DF > DE
16 + DF > 37
DF > 21
Now, for the upper maximum, we know that the two given lengths must be greater than the length of DF. So again, we can solve for the maximum using the amounts.
DE + EF > DF
37 + 16 > DF
53 > DF
With these two in mind, we know that DF must be between 21 and 53
