Answer:
57°
Step-by-step explanation:
Let's assume the measurement of the second angle is x.
so, following the problem
(2x + 9) + x = 180
2x + x = 3x
=> 3x + 9 = 180
=> 3x = 180 - 9
3x = 171
x = 171/3
x = 57°
57° is the smallest angle
x=22/3 is your answer
Answer: 55
By the alternate exterior angles theorem,
x=17
the two segements equal each other, so make teh equations equal eachother and solve for x ,2x-10=x+7
