7 0

Answer:

x = 21

Step-by-step explanation:

given : angle a = 75

we need to find the value of x.

To find the value of x.

we know that it is a straight angle so the sum of angles on a line will be 180

3x + 2x + a = 180

5x + 75 = 180

5x = 180 - 75

5x = 105

x = 105/5

x = 21

Answer:

Step-by-step explanation:

(f+g)(x) ➡ f(x) + g(x)

x/2 - 2 + 2x^2 + x - 3 = 2x^2 + 3x/2 -5
