Question

PLZ HURRY. find angle b I NEED HELP FIGURING OUT HOW TO DO THESE ROBLEMS IN GENERAL​

Answer 1

b=42°

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.

`90-48=42`

2) B=42°
