Answer:

2 1/4

Step-by-step explanation:

Number 1 is incorrect because 1/4 x 9 is 2 1/4 not 1 1/4.

To multiply fractions, multiply directly across. So multiply 1/4 x 9/1 to get 9/4 which converted into a mixed number is 2 1/4.

I need to find measure of angle "u" m
garik1379 [7]

Answer:

30°

Step-by-step explanation:

TW UV

If an ARC subtends an angle in the circle (on the opposite side of the circumference), the measure of that angle will be HALF of the Arc. In other words, the Arc's measure will be DOUBLE of that angle.

The measure of the angle would be SAME if the angle subtended in the center of the circle, thought.

Now, looking at the image, we can see that:

Arc TW subtends Angle V and Angle U

*on the opposite side of the circumference*

So,

Angle V (measure given to be 30) is HALF of Arc TW, so

Arc TW = 2 * 30 = 60

So, Angle U is half of Arc TW

60/2 = 30

Hence,

<u>∠U = 30°</u>
