I know because i took this nightmare of a test and almost had a mental breakdown
Quartz, feldspar, mica, amphibole, pyroxene, and olivine
Answer:
c=49 degrees
b=131 degrees
Explanation:
Angle c and the angle that measures 49 degrees are opposite angles. Opposite angles are equal to each other, so we can conclude that angle c is equal to 49 degrees.
c=49 degrees
Angle c and angle b are both sitting on a straight line, and a straight line has an angle measure of 180 degrees. To find angle b, we can subtract 49 from 180.
b=180-49
b=131 degrees
Therefore,
c=49 degrees
b=131 degrees
I hope this helps!
