Answer:

B. m∠EBG =45° is acute & m∠ABC = 180°

Explanation:

When faced with multiple angle in a single protractor, you first need to isolate the certain angle being asked for.

Take a look at the first image with the blue lines. The angle line are clearly in the 125° and the 80° area of the protractor.

Now we know that all acute angles are any angle that are less than 90°.

Let's solve for how the angle became 45° by subtracting the two angle measurements together.

125° - 80° = 45°

45° < 90° making it an acute angle.

Now take a look at the second image with the red lines. A straight angle is an angle that has a total of only 180°. Anything other than 180° is NOT a straight angle.

So now that we have the measurements of both of them, the answer is letter B. m∠EBG =45° is acute & m∠ABC = 180°
