Array:
1
1this is the Y axis
1
1
111111111111 this is the X axis
so there's a y axis and x axis.
You need to count how many dots AKA 1's are
on the x axis and y axis and multiply them.so in
this case it would be 5 times 12 so the answer would be 60.
Your answers are ...
1) <span>Arc PQ is congruent to arc SR.
2) </span>The measure of arc QR is 150°.
4) <span>Arc PS measures about 13.1 cm.
5) </span><span>Arc QS measures about 15.7 cm.
All of them are correct except for the third answer...
Hope this helps!</span>
Use PEMDAS. 20/(4*5)=1
Multiplication before dividion
