The probability of landing on a shaded sector is 2/5.
The measure of a straight line is 180
125+30=155
180-155=25
x = 25
(3x+4)(2x+1)
If the question asks you to find roots/solutions:
3x + 4 = 0
3x = -4
x = -1.33333333
2x + 1 = 0
2x = -1
x = -0.5
According to the trigonometric functions, we can see that angle x can be found through the one that involves the adjacent side and the hypotenuse, which in this case is the cos,

then, if we apply the inverse we can find the value of x,
