(a) Name the minor arc __________ Name the major arc ___________

iragen [17]

Answer:

Part a) minor arc: XY; major arc: XVY

Part b) $248\°$

Part c) The tangent line is UV and the secant line is XY

Part d) $UV=6\sqrt{5}\ units$ or $UV=13.42\ units$

Step-by-step explanation:

Part a) we know that

The major arc is the larger arc joining two points on the circumference of a circle. Is an arc larger than a semicircle.

The sum of major and minor arcs is the whole circle, 360°

In this problem, possible major arcs are

VYX, VXY, XVY

and the corresponding minor arcs are

VX, VY, XY

Part b) we know that

The sum of major and minor arcs is the whole circle, 360°

Let

x------> measure minor arc

y-------> measure of major arc

$x+y=360\°$

we have

$x=112\°$

substitute

$112\°+y=360\°$

$y=360\°-112\°=248\°$

Part c) we know that

A tangent line intersects a circle at exactly one point.

In this problem

The tangent line is UV

A secant line intersects a circle in two points.

In this problem

The secant line is XY

Part d) we know that

The Intersecting Secant Theorem States: When two secant lines intersect each other outside a circle, the products of their segments are equal

$UV*UV = UX*UY$

$UV^{2} = 9*(9+11)$

$UV^{2} = 180$

$UV=\sqrt{180}\ units$

Simplify

$UV=6\sqrt{5}\ units$ or $UV=13.42\ units$

WINSTONCH [101]

Answer:

32 people

Step-by-step explanation:

If 3/4 equals 24, we need to find the other fourth. We can divided the total number of people by the numerator. 24/8, then add 8, which equals 32.

The ratio of the measures of three angles in a triangle is 14:5:11. Find the measures of the angles

EleoNora [17]

Answer:

84 degrees

30 degrees

66 degrees

Step-by-step explanation:

14 + 5 + 11 = 30

180/30 = 6

14 × 6 = 84 degrees

5 × 6 = 30 degrees

11 × 6 = 66 degrees

The probability a bus will be full is 65% which words or words best describes the likelihood the bus will be full?

allsm [11]

Due to the fact that the question states there is a 65% chance the bus will be full, that is a very high probability. Therefore, there is only a 35% chance it wont be full. Or you can say it in fractional form: 65/100 chance of it being full, and a 35/100 chance of it being less than full.
