Sorry I don´t know the answer but I tried

Step-by-step explanation:

x° = 99°

Step-by-step explanation:

Sum of angles on a straight line is 180°.

Sum of angles in a triangle is 180°. Let u be the value of the unknown angle in the triangle.

u° = 180° - 57° - 42°

u° = 81°

Sum of angles on a straight line is 180°.

x° = 180° - 81°

x° = 99°

d. 9

step-by-step explanation:

in the table given in the picture, x is the input of the function and f(x) is the output on the given input. in the given table, it can be read as the value of function at -3 is it's respective value of f(x) which is -9.

as we have to find the value of f(3), we will see that what is the value of output on input 3. we can see in the table that the output value at x=3 is 9.

so, option d is the correct answer ..
