Answer:

Remember, the formula is the second value minus the first value, divided by the first value times 100.

9. 50% Increase

10. 33% Decrease

11. 200% Increase

To calculate tip, simply move the decimal place 2 to the right and multiply it by the price. For example, If you want to leave a 20% tip, multiply the cost by 0.20 to get the tip amount or multiply the cost by 1.20 to get the total including tip.

N trapezoid ABCD, find m∠A if m∠B= 25°, m∠C = 155° and m∠ D= 117°. A) 25° B) 63° C) 73° D) 92°
ExtremeBDS [4]
Sum of the angles of the trapezoid (quadrilateral) add up to 360°, so based on available information 
mâ A + mâ B + mâ C + mâ D = 360° relates to mâ A + 25° + 155°
+ 117°.=360°
So,  mâ A = 360° - (25°+155°+117°)
mâ A = 360° - 297°
mâ A = 63°
