Okay so the value of X is 9x^2/7
Answer:
The measure of the third arc is 
Step-by-step explanation:
step 1
we know that
The measurement of the external angle is the semi-difference of the arcs which comprises
in this problem
Let
x----> the greater arc of the circle intercepted by the secant and the tangent
y----> the smaller arc of the circle intercepted by the secant and the tangent

----> equation A

-----> equation B
Substitute equation B in equation A and solve for y

Find the value of x

step 2
Find the measure of the third arc
Let
z------> the measure of the third arc
we know that
-----> complete circle
substitute the values and solve for z


Dude that’s not an answer
Step-by-step explanation:
TS = 4x - 7
x = -7/4
SV = 5x -15
x = -15/5
= -3
TV = -7/4 + -3
= -3 3/4
= -4.75
