a )
First of all we need to find the value of x ,
because the angles are written in terms of the variable x .
______________________________________
<h2>Let's find the value of
x :</h2>
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.
The answer is d (fohog)= 4x-5/4x-9
1 2/3 = 5/3
2 3/4 = 11/4
5/3 ÷ 11/4 = 5/3 × 4/11
= 20/33
a. I agree because ΔVWS is a 180° rotation of ΔXWV, and the points match up.
b. It is a SAS congruence postulate and it's just a 180° rotation and the points match up.
That's what i put I don't know if its correct
