What is the value of x? Please provide an explanation, thanks!
Novosadov [1.4K]

Answer:

28

Step-by-step explanation:

What you do is add up 42 and 76, then you subtract that from 180, because all triangles add up to 180. the subtracted amount is what z equals. Then since its a straight line you know it adds up to 180. You add z (62) and 90 because its a right angle. then you subtract 180 by 152 to get 28.

HELP PLEASE WILL MARL BRANIEST IF right
Kaylis [27]

Answer:

A bit of a doosy, but bare with me: f*g*h(x) = x^2+54x-12x\sqrt{x} -108\sqrt{x} +90

Step-by-step explanation:

So explaining this is a bit awkward as well, but I can try...So

Starting from g(x) working that backwards into f(x), so...

g(x) = x-3

f(x) = (x^4+9)

Take your g(x) and plug it into your f(x) into every x you see

f(g(x)) = (x-3)^4+9 ~ I hope you can visualize this, but do you see how g(x) plugs into f(x)...

Now you still have one more step which you still need to include h(x), so

Remember h(x) = \sqrt{x}

Now plug in your h(x) into every x you see from f(g(x)) and it should look like...

(\sqrt{x} -3)^4 + 9
