Remark
The law of chord intersection is that each chord from one point on the circumference to the intersect point when multiplied by the left over amount of the chord = the same thing done to the other chord. It's easier to understand the formula used to solve this problem than it is to work through the definition.
Equation
x*4 = 14 * 2
Explanation
Take x from the chord's end on the circumference to the intersect point and four's length from the intersect point to the circumference. Multiply them
Do the same thing with the other chord.
Solution
4x = 28 Divide by 4
x = 28/4
x = 7
Answer:
and
Step-by-step explanation:
Given a polynomial with rational coefficients, its irrational and complex roots would occur in conjugate pairs.
For example, if the roots of a polynomial are 2 + , 3 and 4 - 3i, then 2 - , and 4 + 3i are also roots of the polynomial.
Therefore, since the given polynomial has rational coefficients and some of its roots are , and - , then - and are also roots of the polynomial.
Answer:
x = 20
Step-by-step explanation:
first, you would take all of the angles and add them up to 180
2x+40+100=180
second, we combine like terms
2x+140=180
third, we solve for x
2x+140=180
-140 -140
2x=40
x=20
i hope this helps!
Answer:
45
Step-by-step explanation:
It would be C. since the -7 means you move 7 units downwards on the graph, and E. since smaller slopes are wider, whereas larger slopes are more narrow
