Answer:
14
Add the lengths of all sides together, I would recommend graphing to see for future reference!
Answer: Choice D
Explanation:
I'll use the point-slope form to get the following
You should find that plugging x = -4 into equation D will lead to y = 1 as a way to confirm the answer.

Answer:
Next term = -16
Step-by-step explanation:
0-4 = -4
(-4)-0 = -4
(-8)-(-4) = -4
(-12)-(-8) = -4
It’s clear that Un is an arithmetic sequence of common difference r = -4
Then
Next term :
Given the sides 11,13,19, to calculate for the smallest angle using cosine rule, i.e;
a^2=b^2+c^2-2bc cos (A)
we shall proceed as follows;
The smallest angle is always opposite to the shortest side; Since 11 is our shortest side, the smallest angle is the angle opposite to this side. Thus;
let a=11 and our smallest angle be A
thus
11^2=13^2+19^2-2*13*19 Cos A
121=169+361-494 Cos A
121=530-494 Cos A
-409=-494 Cos A
dividing through by -494 we get;
Cos A=0.8279
thus
A=Cos(-1) 0.8279
A=34.113°≈34°
The answer is A=34°
