Answer:
15/17
12/37
12/13
20/21
Step-by-step explanation:
5)
cos A = adj/hyp = 15/17
6)
cos C = adj/hyp = 12/37
7)
cos Z = adj/hyp = 36/39 = 12/13
8)
tan A = opp/adj = 20/21
Answer:
2 times
Step-by-step explanation:
the length and breadth of the parallelogram will be l and b, respectively.
Then, perimeter = 2(1 + b) [∵ perimeter of parallelogram = 2 x (length + breadth)]
If both sides are increased twice, then new length and breadth will be 21 and 2b, respectively.
Now, new perimeter = 2(21 + 2b) = 2 x 2(l + b) = 2 times of original perimeter.
the perimeter of parallelogram will be increased 2 times.
