I believe the correct answer is A,
Answer:
x = 70°
Step-by-step explanation:
Clockwise from top, call the three tangent points A, B, and C. Central angle AXC is the supplement of the marked external angle, so is 140°. Arc AB is bisected by the upper ray of angle x; and arc BC is bisected by the lower ray of angle x. That is to say x is half the measure of arc AC, so is 70°.

Attached is the output of a geometry program. The angle at lower left is 40° as in the given figure. The central angle α (70°) remains the same as tangent point C is moved around, which is to say that the measure of the angle α does not depend on the dimensions of the triangle containing α. It just depends on the fact that the triangle is tangent to the circle.
Answer:

Step-by-step explanation:
You multiply 9 x 3=27
(leave 1/3 alone, it's already good)
you have a 27/3-1/3
(subtract those)
your answer is 26/3
(see answer above for decimal form and mixed fraction form)
Answer:
-19,531,250
Step-by-step explanation:
multiply the last term by -5
He will need 2/3 of a cup.
You can do this by setting up a proportion, so
(2/3)/(3/4) = x/1.
Then you would get 2/3 = 3/4x
Divide both sides by 3/4
X = 8/9
