Answer:
141
Step-by-step explanation:
Angle Formed by Two Chords= 1/2(SUM of Intercepted Arcs)
We know z+70 = 180 since they form a straight line
z = 110
z = 1/2 ( 79+w)
110 = 1/2 ( 79+w)
220 = 79+w
220-79 = w
141 =w
Answer:
- Both have 4 imaginary roots
Step-by-step explanation:
1)
1.
- x^2 + 9 = 0
- x^2 = - 9
- x = ± √-9
- x = ± 3i
2.
- x^2 + 6 = 0
- x^2 = -6
- x = ±√-6
- x = ± i√6
It has 4 imaginary roots and no real roots
2)
1.
- x^2 + 7 = 0
- x^2 = -7
- x = ± √7
- x = ± i√7
2.
- x^2 + 5 = 0
- x^2 = - 5
- x = ± √-5
- x = ± i√5
It has 4 imaginary roots and no real roots
You're looking for values to factor this equation into (x+p)(x+q)
such that pq=12 and p+q=b
Assuming we're looking for simple values, you can start by factorizing 12:
12 = 3*4 = 2*6 = 12*1 = -3*-4 = -2*-6 = -12*-1
For 3 and 4, b would be 7
2 and 6 => b=8
12 and 1 => b=13
and for the negatives
b can be -7, -8 or -13
So the total set is -13, -8, -7, 7, 8, 13
