Answer:
Solution (7,1)
Step-by-step explanation:
Use the elimination method
x + y=8
x - y=6
--------------Add
2x = 14
x = 7
Substitute x = 7 into x + y=8
7 + y=8
y = 8 - 7
y = 1
Solution (7,1)
Answer: First option.
Step-by-step explanation:
You can idenfity in the figure that
is formed by two secants that intersect outside of the given circle.
It is important to remember that, by definition:

Knowing this, you can set up the following equation:

Therefore, you must substitute values into the equation and then evaluate, in order to find the measure of the angle
.
This is:

The perimeter of an object is found by adding all of the sides. The sides of his frame would be 2 ft, 2 ft, 1.5 ft (18 inches / 12 inches per foot = 1.5 feet), 1.5 feet. Adding these together we get a total length of 7 feet. However, he may want to use a slightly longer board to account for any errors!
