The measure of angle AEB is 19 degrees
Making a list can help you solve a problem by:
•making more organized
•it can make it easier to organize data
•helps you stay on track
those are some of the basic ways,
Okay. For these types of problems, you must do order of operations (PEMDAS). Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction. Mind you that you do these steps from left to right, and multiplication and division is done from left to right. Same thing with addition and subtraction. With that being said, here are your answers if you do the expressions correctly.
1. 12
2. 106
3. 42
