* ANSWER PLS!! * I need to know the value of x. since i got the other answer wrong.
thank you!!!

19.5

Step-by-step explanation:

BY THE SECANT/TANGENT SEGMENT LENGTH THEOREM

= 10 x (28 + 10) = 10 x 38 = 3819.50

x = square root of 380 = 19.49358869 (approximately 19.5)

OPTION A

***SECANT/TANGENT SEGMENT LENGTH THEOREM

If a secant and tangent are drawn from a common exterior point, then the

product of the length of the secant with the length of its external

segment is equal to the square of the length of the tangent.

welll its a very hard question but ill

step-by-step explanation:

first you take the 6 dollars and add 10 to it then add the 50 to that then multiply by 8 with xy and your answer will be

hope this

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
