Answer:
angle A is 112 degree.
Step-by-step explanation:
quadilateral have 4 angles .
sum of the interior angles of a quadilateral is 360 degree
Here,
angle A = be x
angle B = 122
angle C = 75
angle D = 51
Now,
angle A + angle B + angle C + angle D =360 degree
x + 122 + 75 + 51 = 360
x + 248 = 360
x = 360 - 248
x = 112
Zeros
x = -3 point (-3 ,0)
x = 3 point (3 ,0)
Using a graphing calculator, we can easily check the intercepts of the equation
y = -x^2 +9
x^3 = 64/27
x^3 = (4*4*4)/(3*3*3)
x^3 = (4/3)^3
x = 4/3
