The answer is 10 ft. make a triangle 6ft tall, 8ft long (90 degrees to the other line) and draw a line to complete the triangle. This is a type of 3,4,5 triangle, a 6,8,10. The other way to do it is sqrt(6^2+8^2) = sqrt(36+64) = sqrt (100) = 10.
Answer:
64 1/2
Step-by-step explanation:
5x12=60
3/8x12/1= 36/8= 9/2 9/2=4 1/2
60+4 1/2= 64 1/2
Answer:
6 Meters long
Step-by-step explanation:
3+3=6
12-6=6
<span>rotation of 180° about the origin is correct. Changing the signs of both x and y rotates 180 degrees.

The result follows directly from properties of modular arithmetic:
That is,
means we can write for some integer . Then
and taken mod 12, the first term goes away, so
etc
