X - 8 = 23
x = 23 + 8
x = 31 <== originally on their 31 yard line
Answer:
The answer is C: They are all the same.
7) • A straight line is 180 deg
• So B = 180-138 = 42 degrees
• Isosceles triangles have equal angles on the equal sides
• So G = 42 degrees
• We know a triangle has 180 degrees
• So 180 - 42 - 42 = 96 degrees for A
8) • Use similar logic to above
• TCB = 180 - 87 = 2x
• TCB = 46.5 degrees
• ACB = 180 - 65 = 2x
• ACB = 57.5 degrees
• TCB + ACB = ACT = 104 degrees
Let w and l be the length and height of the rectangle.
We know that:

Substitute the first equation in the second:

Use the first equation to compute the length:

So, length = 7 cm; width = 6 cm
