Find the difference 7 7/8- 3 1/4
grigory [225]
The mixed number have to become a improper fraction and then you have to subtract like this.

so 7 7/8 you have to multiply 7 times 8 and then add it by 7 .
You do the same thing with the other mixed number 3 times 4 plus 1 

So the first one is 63/8 - 13/4 =

first the 4 in the 13/8 have to become 8 . so you do 4 times 2 = 8 and multiply the 13 by 2 = 26 .
so equal 

63/8 - 26/8 = then you have to do 63 - 26 = 37 so is 37/8 and then simplify or divide .

when you divide you suppose to get 4 5/8

Circle T is shown. Line segment Q S is a diameters. Point R is opposite of point T. Lines are drawn from points Q and S to point
Juliette [100K]

The value of angle x of the given cyclic segment is; 49.5°

<h3>How to find the angle of an arc?</h3>

We are given the measure of the angle of  arc QS as (4x – 18)°

Now, to find the measure of arc QS, this angle is to be equal to 180° and as such;

Thus;

(4x – 18)° = 180°

4x - 18 = 180

4x = 180 + 18

4x = 198

x = 198/4

x = 49.5°

The angle subtended by the arc at the center of a circle with center C is the angle of the arc. It is denoted by. m AB, where A and B are the endpoints of the arc. With the help of the arc length formula, we can find the measure of arc angle.

The formula to measure the length of the arc is;

Arc Length Formula (if angle θ is in degrees); s = 2πr (θ/360°)

Arc Length Formula (if θ is in radians) s = ϴ × r.

Thus, the value of x of the given cyclic segment is; 49.5°
