(3 * 10,000) + ( 9* 1,000) + ( 5* 1)
Answer:
D. 6
Step-by-step explanation:
Let's first find x :-

Now that we found x, let's find QR :-
QR = 2x + 22
Therefore, QR = 6 !!!
Answer:
x=45 degrees
Step-by-step explanation:
You can see based off of the markings on the 2 sides, that it is an isosceles triangle, so that means the 2 base angles are equal.
so 2x+90=180 degrees
so 2x=90 degrees
x=45
Let's use the distance formula:

So it is:
AB :

BC:

CA:

So 9.43 + 5 + 8 =22.43
