Answer:
144°, 144°, 36°, 36°.
Step-by-step explanation:
Take shorter angle = x
Then the bigger angle = 4x (4 times the other angle)
In a parallelogram, there are 4 angles. Also, in a parallelogram opposite angles are equal to each other.
So,
1 angle = x
2 angle = 4x
3 angle = x
4 angle = 4x
The sum of all 4 angles in a parallelogram = 360°. So,
4x + x + 4x + x = 360°
10x = 360°
x = 360/10
x° = 36°
4x = 36 × 4 = 144°
Angles in the parallelogram = 144°, 144°, 36°, 36°.

Answer is C
Y-y1=m(x-x1)
y1=-1/2 x=4/5, m=3/4
<span> y^2 = (3x + 1)^3 / 9x + 2
2*y*(dy/dx)=(9</span>(3x + 1)^2*(9x + 2) -((9*(3x + 1)^3))/ ((9x + 2)^2)
(dy/dx)=(9(3x + 1)^2*(9x + 2) -((9*(3x + 1)^3))/ (2*y*(9x + 2)^2)
(dy/dx)=(9(3x + 1)^2*(6x + 1))/ (2*y*(9x + 2)^2)
answer
A
