Answer:Do you mean find p? If so then p+10 = 90 - 49, so p = 31°. Another possibility is in the second quadrant where p + 10 = 180 - 41 so p = 129° (The 41 comes from the first p+10, i.e. 31+10 = 41),

Step-by-step explanation:
21 because you have to have at least 1 side as 3m so the other two should be 9m to have the greatest possible length
Answer:
Step-by-step explanation:

we take the LHS so here goes,

since ,
the identity becomes,

now, we know,
and 
the identity becomes,


sin A and cos A cancel out it becomes zero

Splitting the denominator the identity becomes

Hence,

2500 because 25% of 2000 is 500 and 2000+500 is 2500? tell me if im wrong!
