In the pictured triangle, ZA is 137 degrees and ZB is 28 degrees. If side bis 71 units long, approximately how long is side a?

a would be 103.14 units approximately.

Step-by-step explanation:

A=137

B=28

b=71

a=?

Using the formula

a/sinA=b/sinB

or, a/sin137=71/sin28

or, sin28a= sin137.71

or, sin28a=48.42

or, a=48.42/sin28

so, a = 103.14

ha!

i just did this!

18. g

20. h 30 degree turn.

21. d 90 degree angles

and also 19 is a. a sphere not a cirlcle

hope i !

pls mark me brainiest

22 and 22

step-by-step explanation:

10 plus 12 equals 22.

12 plus 10 also equals 22 because regardless of what order they're in, they're gonna equal the same thing.
