Answer:
x= (1,8)
Step-by-step explanation:
This is an incorrect question, the correct question is given below.
Martin is building a model. He cuts two pieces of wood that are each inches long from a board with a total length of 18 inches. What is the length, in inches, of the remaining part of the board?
Answer : The length of the remaining part of the board is inches.
Step-by-step explanation :
As we are given that:
Total length of the board = 18 inches
Length of each piece of wood cut from the board = inches = inches
Length of 2 pieces of wood cut from the board = inches
= inches
Length of the remaining part of the board = Total length of the board - Length of 2 pieces of wood cut from the board
Length of the remaining part of the board = inches
= inches
= inches
= inches
Therefore, the length of the remaining part of the board is inches.

Answer: Choice A) 148 degrees</h3>
==========================================================
Explanation:
Let point A be the center of the circle.
Arc DCF is 316 degrees. Arc FG is 20 degrees. Subtracting the arc measures gives 316-20 = 296 which is the measure of arc DCG, and by extension, it is the measure of reflex angle DAG. The acute angle DAG is 360-296 = 64 degrees
Triangle DAG is isosceles with AD = AG, so the base angles are ADG and AGD. Let's call each of these angles x for now. The sum of the three angles add to 180
x+x+64 = 180
2x+64 = 180
2x = 180-64
2x = 116
x = 116/2
x = 58
Therefore angle ADG is 58 degrees. It adds to angle ADB = 90 to get 90+58 = 148, which is the measure of angle BDG.
Note: angle ADB is 90 because tangent BD forms a right angle with the radius AD.
Another note: angle ADG is half that of the arc it cuts off, so in a sense it's similar to an inscribed angle
