Put the protractor so that one of the rays passes through 0^(∘).
40^(∘)
Practice makes perfect
We want to measure the angle. To do so, we will use a protractor.
We put the protractor so that one ray travels through 0^(∘). We can see that the other ray passes through 40^(∘). This means that the measure of the angle is equal to 40^(∘).
