We don’t know what was taught in the lesson, so we’re just guessing what your book/teacher said. However, the most common tire rotations are usually B or C.
B) -4
5b=6a+16
9a=7b-20
b=(6/5)a+(16/5)
9a=7((6/5)a+(16/5))-20
9a=(42/5)a+12/5
(3/5)a=12/5
a=4
5b=6(4)+16
5b=24+16
5b=40
b=8
3(4)-2(8)
12-16=-4
Answer:
Angles are measure of rotation, along with its direction of rotation. The supplement angle of 77° is 103°
How to find the supplement angle of an angle?
Supplement angle of an angle is such that sum of both of them comes as 180°
Thus, if an angle is of A°, then its supplementary angle is 180° - A°
For the given case, we let the first angle be of A° = 77°, then its supplementary angle with measure B° is:
Thus, The supplement angle of 77° is 103°
