4.Complete each of the following BRAINIEST and 50 points its just Trigeometry​

#1:

cos a = opp/hyp = cb/ca

tan a = opp/ajd = cb/ab

sin c = adj/hyp = ab/ca

cos c = opp/hyp = ab/ca

tan c = opp/adj = ab/cb

2: *i dont have the square root symbol*

sin 60 = 3/2

cos 60 = x/2

tan 60 = 3/x

sin 30 = x/2

cos 30 = 3/2

tan 30 = x/3

3: *i dont have the square root symbol*

sin 45 = 2/x

cos 45 = x/2

tan 45 or 48 = x/y

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490

1) c 2143.6 cm

2) c 113.0 m

3) a 33.5 ft

4)   d 2 cm

5) c 20 mm

6) 180 in

7) d 120 ft
