Angle of a straight line always sum up to 180 degrees
So what you should do is add the angles that are given to you and then subtract it from 180
Working:
100 + 20 + x = 180
120 + x = 180
x = 180 - 120
x = 60 degrees

I hope this helps you and your welcome

Let f(x) = x2 + 6 and g(x) = x + 8x . Find ( g o f)( -7)

Artyom0805 [142]

Answer: $(gof)(-7) =495$

Step-by-step explanation:

Given the functions f(x) and g(x), to find $(gof)(x)$ you need to substitute $x=f(x)=x^2 + 6$ into the function g(x):

$(gof)(x) = ( x^2 + 6)+ 8( x^2 + 6)\\\\(gof)(x)=x^2 + 6+ 8x^2 + 48\\\\(gof)(x)=9x^2 + 54$

Now, to find $(gof)(-7)$ you must substitute $x=-7$ into $(gof)(x)$ , then you get:

$(gof)(-7) = 9(-7)^2 + 54\\\\(gof)(-7) =9(49)+54\\\\(gof)(-7) =441+54\\\\(gof)(-7) =495$
