Work out the size of angle x

ill mark brainliest first corect answer!​

65°

Step-by-step explanation:

First we find the sizes of the other two sides, as the bottom line is straight all angles on it must add up to 180 so:

180-105=75

So the first angle is 75°

180-140=40

So the second angle is 40°

Now as the angles of a triangle add up to 180 we can derive this equation:

75+40+x=180

and all we do is just subtract both sides by 75 and 40:

x=180-75-40

x=65

And 65 is our answer

2 x^2 -3x+p

sum of roots = 3/2

let other root be x

3+ x = 3/2

x= 3/2 - 3 = -3/2

product of roots = p/2

3× -3/2 = p/2

-9 = p

⭐⭐

answer: all the values are within because it has a pattern that repeats from -6 to 4.

good luck!
