I'm guessing dilation of magnitude 6 centered at the origin
Answer:
Yeah it's 10
Step-by-step explanation:
100/10=10
Because in an equilateral triangle all angles should measure 60 degrees otherwise all sides would not be equal.
Answer: a = 15
Step-by-step explanation:
6a + 10 = 3a + 55
Subtract 10 from both sides
6a = 3a + 45
Subtract 3a from both sides
3a = 45
Divide each side by 3
a = 15
