What is the measure of angle 𝐵𝐴𝐶?
00:00:04.820 --> 00:00:09.490
Well 𝐵 is here, 𝐴 is here, and 𝐶 is here.
00:00:11.050 --> 00:00:17.160
And this means in order to measure angle 𝐵𝐴𝐶, we’re looking for the size of this angle here.
00:00:18.740 --> 00:00:25.240
Now luckily the whole question has been presented on top of a protractor and better than that it’s even been properly lined up.
00:00:25.540 --> 00:00:33.150
We’ve got 𝐴 at the main point here and then we’ve got the line 𝐴𝐵 mapped along the baseline of our protractor.
00:00:34.260 --> 00:00:42.160
So all we have to do is start counting at zero and follow up this scale here to see what angle is measured.
00:00:44.000 --> 00:00:46.990
And it goes wonderful notch further than ten.
00:00:47.380 --> 00:00:51.120
Each of these little notches on a scale represent one degree.
00:00:51.150 --> 00:00:53.970
So that’s ten plus one is eleven degrees.
00:00:55.160 --> 00:00:59.570
And that’s our answer: the measure of angle 𝐵𝐴𝐶 is eleven degrees.
