The answer is B !!!!!!!!’nnnnnnsnnaamajsnkanaksnss
Step-by-step explanation:
(x +40)° = 60°
60°- 40°=20°
x = 20°
4/x³ - (2x-1)/3x
= (4*3) - (2x-1)(x²) / 3x³
= (12 - 2x³ - x²) / 3x³
= -2x³ -x² + 12 / 3x³
The answer is C.
Hope it helps!

Let's solve for value of values of x and y ~
According to Angle sum property of triangles :




Now, solve for y ~




Now, by the results we got, we can conclude that :
The two triangles are not similar because 70 + 58 + x = 180 means x = 52° and 70 + 49 + y=180 means y = 61°
