Answer:
150
Step-by-step explanation:
The angle as a whole is 180 degrees. 150 and 30 are supplementary angles because they add up to equal 180.
Ok.graph the 2.3 and the 6.8 as regular decimals, draw a line, annd I dont know how to do the last part. :(
Make a ratio, then cross multiply.
4/30=x/48
30x=4x48
30x=192
x=6.4
