Answer:
∠ ABC ≈ 137.9°
Step-by-step explanation:
Using the Cosine rule in Δ ABC
cos B = 
with a = 89, b = 144, c = 65
cos B =
=
=
, thus
B =
( -
) ≈ 137.9° ( to the nearest tenth )
It is 0.09. this is because you do 3 multiply by 0.6. then you do 1.8divided by 20 because you want per one minute so that becomes 0.09 and that is your answer. Hope this helps I am really close to ranking up so if you can award me the most brainliest that would be great!! thanks and your welcome
