Answer:
A. 90°
B. 134°
C. 46°
Explanation:
A. First you can see that A is a 90 degree angle. You can tell that it is because its the angle of two straight lines meeting like the corner of a square.
C: Every triangle's corners add up to 180 so all you have to do is subtract the other corners from 180. You can find the last corner because it is a pair with angle A. Also 90 degree angles are often labeled with a small square. So to find angle C add 44 and 90:
44+90=134
then take that product and subtract it from 180
180-134= 46
That's the angle for C.
B. Then to solve for B then line B and C are on will have a total angle of 180. All straight, flat lines have an angle of 180. If you know one of the sides, or can solve for it, then you can find the other angle. We already know what C is so we just need to subtract that from 180.
180-46=134
Which is almost the same problem as for C.
Hope this helps!
