Find length BC

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

1.0cm

Step-by-step explanation:

tan 29 = BC/AB

0.554 = BC/1.8

BC = 0.9972

     = 1.0cm

1 cm

Step-by-step 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

phosphate, calcium ion, chloride ion, neon atom

step-by-step explanation:

38.6°

step-by-step explanation:

resultant is 10 pound

smaller force = 8 pound

angle formed = tan⁻¹(

                        =tan⁻¹(

                          =tan⁻¹(0.8)

                        =38.6°
