Answer:
negative; -1/4
Step-by-step explanation:
The correct angle measures are m/JKL = 37° and mZKLM = 126°. Option A and C
<h3>How to determine the angle</h3>
Given that;
∠ K = (4x + 5)°
∠ J = 6x + 1
∠ L = 8x + 30 = 180 ( angles on a straight line)
Note that the sum of the angles of a triangle is 180°
∠ K + ∠ J + ∠ L = 180
6x + 1 + 4x + 5 + 8x + 30 = 180
collect like terms
18x = 180 - 36
18x = 144
Make 'x' the subject
x = 144/ 18
x = 8
Substitute the values
∠ JKL = (4x + 5)° = 4(8) + 5 = 37°
∠KJ L = (6x + 1)° = (6(8) + 1) = 49°
∠ KLM = 8x + 30 = 8(8) + 30 = 94°
∠ JLK = 8x + 30 = 180 = 180 - 94 = 86°
Thus, the correct angle measures are m/JKL = 37° and mZKLM = 126°. Option A and C

We can work out the first three terms of this quadratic equation with substitution.
The first term of this sequence is where n=1, we can substitute 1 in for n
y=1^2+2(1)-4
y=1+2-4
y=-1
We can do this for the next two terms as well
y=2^2+2(2)-4
y=4+4-4
y=4
For the last term:
y=3^2+2(3)-4
y=9+6-4
y=11
Rounded to the nearest tenth is 585.1
