Answer:
∠ AOB = 139°
Step-by-step explanation:
Since AOC is a straight line then
∠ AOB + ∠BOC = 180° , that is
8x + 51 + 6x - 25 = 180
14x + 26 = 180 ( subtract 26 from both sides )
14x = 154 ( divide both sides by 14 )
x = 11
Then
∠ AOB = 8x + 51 = 8(11) + 51 = 88 + 51 = 139°
1/2 9 goes into 18, 2 and 9 goes into 9 once.
It will cost 4.24 because 6% of 4.00 is .24 cents
Answer:
1
Step-by-step explanation:
For any triangle, you only need to know 3 pieces of information out of the 6 angles and sides to solve for the rest of the triangle.
Since it is a square, the angles are 90 degrees. The diagonals would bisect the angle in half so the angle PRS would be equal to 45 degrees.
