PLZ HURRY. find angle b I NEED HELP FIGURING OUT HOW TO DO THESE ROBLEMS IN GENERAL
1 answer:
Answer:
b=42°
Step-by-step explanation:
This angle is an example of a complementary angle. This means that the total sum of its angle is 90°.
To work out the value of b you would simply minus the angle of 48 from the total of 90, this gives you 42°. This is because as the total is 90 and the value given is 48 and so to isolate the value of b you would minus the value given from the total.
1) Minus 48 from 90.
2) B=42°
