Answer:
69
Step-by-step explanation:
All the given arcs cover the entire circle circumference, so their measures add up to a full 360.
(2x - 16) + (x + 40) + x + 60 = 360
4x + 84 = 360
4x = 276
x = 69
Answer:
Taking the square root
Step-by-step explanation:
Alternatively, you can use a difference of squares to factor and solve:
An angle can be bisected using just a compass
and straight edge, but it can't be trisected.
Slope: 1.5
Work: I used the slope formula method which is y2 - y1/ x2 - x1. After plugging it in, the new equation is 4 - (-2) / 10 - 6. After subtraction, I had gotten 6/4. And when you divide 6/4, you get 1.5
I hope this helps. :)
Answer:
common denominator of 1/a + 1/b is ab
however simplifying the complex fraction gives: (b-a)/(b +a)
Step-by-step explanation:
common denominator of 1/a + 1/b
should be the product of the denominators
a*b
so 1/a + 1/b = (b + a)/ab
ao
( 1/a - 1/b) divided by (1/a + 1/b) = (b - a)/(ab) divided by (b+a)/ab
