Answer:
To find a
sin 30=a/6in
1/2=a/6in
2a=6in
a=6in/2
a=3in
To find b
cos 30=b/6in
/3/2=b/6in
2b=/3*6in
b=2/3(two radical three)
I don't get the radical sign so I use / sign on the last 3 steps on the second

Answer:
-5 = x
Step-by-step explanation:
First you begin with adding 5 to the other side of the equal sign.
Why? because you want to get "x" by itself, in other words, isolate the variable. and by adding 5 you make 0 on that side
So -10+5 = 5
Therefore -5 = x
