I would assume b ^5 .. add 3 plus 2 and put it as the power or exponent whatever it’s called
85y = 5 * 17y
75 = 5 * 15
so
85y - 75 = 5(17y - 15)
GCF = 5
Answer
5(17y - 15)
Answer: C. He can show that the measures of arcs AB, AC, and BC are all equal to 120°.
Step-by-step explanation:
Each angle of an equilateral triangle measures 60°, so by the inscribed angle theorem, each arc created by a pair of adjacent vertices will measure 120°.
