Perimeter is the sum of all the 4 sides:
Perimeter = L + L + W + W
Given Width = 10 and Perimeter = 68
L + L + 10 + 10 = 68
2L + 20 = 68
2L = 68 - 20
2L = 48
L = 48 ÷ 2 = 24
Length = 24 inches
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.
Answer:
its half of 8 so 8/2=4
