If x = 3 units, y = 5 units, and h = 6 units, find the area of the trapezoid shown above using decomposition. A.
18 square units
B.
33 square units
C.
48 square units
D.
78 square units

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

what is the approximate angle of acb if abc is 25cm and the length of segment bc is 15

step-by-step explanation:

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)
