4x-10 and 7x-8 are supplementary angles and thus add up to 180 degrees.
Thus, 11x - 18 = 180 degrees.
Combining like terms, 11x = 198, and x = 18.
The two supplementary angles are 4(18)-10 and 7(18)-8, or 62 and 118 degrees.
Answer:
yes it would be an obtuse triangle i think
Step-by-step explanation:
I’m not too sure but i think The area of one is 4 inches. There are 8 squares on each side, so when finding the area of the board, you get 64. The checkerboard is 16 inches long, and there are 8 squares, so it is approximately 2 inches long. To find area, you multiply length by width. Since they are squares, it would be 2*2, which leads you to the answer of 4. Hope this helps!

Answer:
-2x^2 + 2x + 1
Step-by-step explanation: If you try to factorize, there are no solutions, and if you use the quadratic formula, you don't get 2 solution for x
