Answer:
a. 18 b. 119°, 118°
Step-by-step explanation:
a. Given angles are vertical, so they are equal.
6a+11 = 2a+83
6a-2a = 83-11
4a = 72
a = 72/4
a = 18
b. Substituting the value of a in the given angles,
6a+11 = 6*18+11 = 108+11 = 119°
2a+83 = 2*18+83 = 36+83 = 118°
Answer:
(-2 + -2 / 2 ; -1 + 4 / 2)
AB Midpoint(-2;1.5)
Explanation:
Use this formula:
Midpoint = (X1 + X2 / 2 ; Y1 + Y2 / 2)
An= -16 + (n-1)7
an= -16 + 7n - 7
an=7n -23
When the rate of change is 7
{a1 = 16, a2=-9, so the rate of rate of change is 7}
