Ответ:
y = -(9) + 7
y = -9 + 7
y = -2 so (9, -2)
Now 7
y = -(7) + 7
y = -7 + 7
y = 0 so (7, -7)
Last one is 0
y = -(0) + 7
y = 0 + 7
y = 7 so (0, 7)
Ответ:
Below in bold.
Step-by-step explanation:
2x + 18 + 3x + 12 = 180 (property of a cyclic quadrilateral).
5x = 180 - 18 -12
5x = 150
x = 30
So m < A = 2(30)+18
= 78 degrees.
