2x^2 + 16x + 34 = 0
x^2 + 8x + 17 = 0
x^2 + 8x + 16 = -17 + 16 = -1
(x + 4)^2 = -1
x + 4 = sqrt(-1) = ±i
x = -4 <span>±</span> i
The answer is 5/7 . 30/2=15 42/2=21 15/3=5 21/3=7
The given diagram represents a quadrilateral inside a circle .
And to find the measurement of angle 1, we have to use the following rule:
Sum of opposite angles of a cyclic quadrilateral is 180 degree.
Here one angle is 86 degree.
![\angle 1 + 86 = 180](https://tex.z-dn.net/?f=%20%5Cangle%201%20%2B%2086%20%3D%20180%20)
Subtracting 86
![\angle 1 = 180 - 86 = 94](https://tex.z-dn.net/?f=%20%5Cangle%201%20%3D%20180%20-%2086%20%3D%2094%20)
So the measurement of angle 1 is 94 degree.
Answer:
angle A and C are both Equal and sides BC and BA of the triangle are congruent

Answer:
If you don't agree or there's an error, let me know so I can edit.
Step-by-step explanation:
f(x) = x⁴ + 2
differentiate
f(x) = 4x³ + 0 =0
x(4x²) = 0
at x= 0 f(x) = 0 points = (0,0)
at x= 1. f(x) = 3 points = (4,3)......
