Answer:
x=4
Step-by-step explanation:
both angles add up to 90* because it is a right angle
10x + 12x + 2 = 90
22x + 2 = 90
subtract 2 from both sides of the equation
22x = 88
divide both sides by 22
x = 4
The angle formed by two tangles results in half of the difference of the two arcs.
That is to say
70 = .5(Major arc - minor arc)
Think of the major arc as the larger and the minor the smaller.
So therefore the difference in the two arcs = 140 (multiplying both sides of the above equation by 2.
140 = major arc - minor arc.
Another necessary idea is that the arc of a whole circle = 360 degrees, that is to say the major arc + minor arc = 360, giving us a second equation to solve.
Assuming x is the minor arc.
140 = major arc - x
360 = major arc + x
Use linear combination and add these equations to get
500 = 2*major arc
major arc = 250
minor arc or x = 110.
The answer is 110 degrees.
Answer:
y=2x + 5 I think it should be
4 + 6 + 3 = 13
1 (total possibility) - 6 / 13 (chance of white ball)
= 7/13
Answer:
C; 7/13
