Find the value of x.

x + 150 = 180

x = 180 - 150

x= 30

then

X = 30

so, when x+ 85 =180

30+85 = 180

115= 180

180-115

= 65

65 degrees

Step-by-step explanation:

Make a triangle with x as one of the degrees. So 180 - 150 = 30 would be another, and 85 would be the other. A triangle's degrees is 180, so 85 + 30 = 115, and 180 - 115 = 65, and that would be the answer.

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
