2 is 37.
to find 1, subtract 37 from 90.
1 is 53.
3 is 143.
That would be 1,132
Please mark me brainliest.
Answer:
Step-by-step explanation:
We have the length of AC which is opposite angle B; we also have the length of the hypotenuse. We will use trig here to solve for angle B. The sin ratio is the one that fits.
sin(B) = side opposite / hypotenuse:
so
sin(B) = .9411764706
Now we will use the 2nd button on our calculators. This will give us the missing angle value. Press 2nd then sin and you will see on your screen:

Enter that decimal after the open parenthesis and hit "enter" to get
B = 70.25 or 70°
