Questions (a, b), 1 (a, b)

a )

First of all we need to find the value of x ,

because the angles are written in terms of the variable x .

______________________________________

STV angle & SUV angle have same measure because both of them are the front angle of SV arc .

So :

Add sides 5

Subtract sides minus 2x

Collect like terms

Thus the measure of angle T equals :

Now just need to put the value of x which we found :

♡♡♡♡♡♡♡♡♡♡♡♡♡♡♡♡♡♡♡♡♡♡

b )

angle S & angle V are also have same measure because they both are the front angles to the TU arc .

And we need to find the value of x again in this part exactly like we did for a .

As the question told :

and ,

Thus :

Subtract sides minus x

Collect like terms

Divide sides by 2

Simplification

So ;

And we're done.

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)
