Triangles equal 180. The bottom left corner is 90 in this triangle. Add the angles together set equal to 180.

x = unknown angle

90 + 67 + x= 180
157 + x= 180
subtract 157 from both sides
x= 23

ANSWER: x=23

Hope this helps! :)

If f(x) = 3x + 10 and g(x) = 2x - 4, find (f - g)(x).

torisob [31]

<h3>Answer: Choice A) x+14</h3>

=======================================

Work Shown:

(f-g)(x) = f(x) - g(x)

(f-g)(x) = (f(x)) - (g(x))

(f-g)(x) = (3x+10) - (2x-4)

(f-g)(x) = 3x+10 - 2x+4

(f-g)(x) = (3x-2x) + (10+4)

(f-g)(x) = x+14
