120, 15
Step-by-step explanation:
Step-by-step explanation:
y = 8x/9 - 2
therefore m = 8/9
x1 = -3
y1 = 6
from, y - y1 = m(x-x1)
y - 6 = 8/9(x+3)
y-6 = 8x/9 + 8/3
y - 8x/9 -26/3 = 0 (×9)
9y - 8x -78 = 0
Answer:

Step-by-step explanation:
The picture of the question in the attached figure
we know that
The measurement of the external angle is the half-difference of the arches that comprise
so

Remember that the sum of the major arc and a minor arc is equal to 360 degrees
we have
----> is given
so

substitute the values
