Answer:

58% of 121 by using 10% is 70.18.

Step-by-step explanation:

58% is about equal to 60%, or 6 times 10%. 10% of 121 is 12.1.

12.1 * 6 = 72.6

To take this further, 58% is 2% less than 60%, or 2 times 1%. 1% of 121 is 1.21.

72.6 - (1.21 * 2) = 72.6 - 2.42 = 70.18

Sin(55) =o/h

=10.4/h

H x sin55 =10.4

÷sin55

H= 10.4/sin55

H=12.7cm

CD is 12.7cm to 3 s.f.
