In circle O, AP = √10, PB = x and BC = 3. Find the value of x.

Artyom0805 [142]

Answer:

The value of x is $2\ units$

Step-by-step explanation:

we know that

Applying the tangent-secant theorem

$AP^{2}=PB*PC$

substitute the values and solve for x

$\sqrt{10}^{2}=x*(x+3)$

$10=x^{2}+3x$

$x^{2}+3x-10=0$

using a graphing tool

to solve the quadratic equation

The solution is $x=2\ units$

Find the missing angles.

raketka [301]

Step-by-step explanation:

x = 90- 55 = 35

y = 180- x

y= 180 - 35 = 145

z =180- (y +10)

z = 180 - (145 +10)

z = 180-155

z = 25

zimovet [89]

The total fabric used for headband and wristband of a player was: 27.84 inches

Step-by-step explanation:

The question will be solved step by step.

So,

Total ribbon used for headbands = 883.68 inches

Total number of people for whom headbands were made = 46 players + 2 coaches = 48 inches

so the headband for one person will use fabric: $\frac{883.68}{48}\\= 18.41\ inches$

Then

Total fabric used for wristbands = 433.78 inches

Total players = 46

$Fabri\ for\ one\ player's\ wristband = \frac{433.78}{46}\\=9.43\ inches$

Total fabric for one player = 18.41 + 9.43 = 27.84 inches

Hence,

The total fabric used for headband and wristband of a player was: 27.84 inches
