Question

Find length BC

i feel like you have to use tan but i’m not sure

Answer 1

Answer: 1 cm

Explanation:

Use sohcahtoa and because you are want to find bc(which is the opposite) and we have been given the adjacent so we use tan

So tan29=o/1.8

x=1.8 on both sides so you get

1.8xtan29=o

O=0.9977562926

Than round it to whatever it needs to be rounded to so I rounded it to 1 decimal place which gives you 1

Answer 2

1.0cm

Explanation:

tan 29 = BC/AB

0.554 = BC/1.8

BC = 0.9972

= 1.0cm
