Answer:

y is 70° and x is 40 °

Step-by-step explanation:

the triangle has two equal sides as shown on the diagram...so the next angle to 110° which is 70° is equal to y....then by calculation y + x should give us 110° so if y is 70 then x is 40.

Answer:

y = 70

x = 40

Step-by-step explanation:

The interior angle connected to 110o is the supplement of the 110o angle.

180 - 110 = 70o

The triangle is marked as having 2 equal sides which means that there must be 2 equal angles opposite these 2 sides. Therefore y is also 70o

All triangles have 180o

Therefore x + y + y = 180

We know the ys = 70 each. Substitute into the equation above

x + 70 + 70 = 180 Combine

x + 140 = 180 Subtract 140 from both sides.

x = 180 - 140

x = 40

$f(x)=x+3;\ g(x)=x^2-2\\\\\left(\dfrac{f}{g}\right)(-1)-g(3)=?\\\\\left(\dfrac{f}{g}\right)(x)=\dfrac{f(x)}{g(x)}\\\\g(3)=3^2-2=9-2=7\\\\f(-1)=-1+3=2\\\\g(-1)=(-1)^2-2=1-2=-1\\\\\left(\dfrac{f}{g}\right)(-1)-g(3)=\dfrac{2}{-1}-7=-2-7=-9$

F(x) = x°-9x

laila [671]

F(x)=x^3-9x
and
g(x)=x^2-2x-3

so you just need to divide f(x) by g(x)

Therefore:

f(x)/g(x) = (x^3-9x) / (x^2-2x-3)

and of course you need to factor these two function to see if some factor would cancel another

x^3-9x = x(x^2-9)=x(x-3)(x+3)
and
x^2-2x-3 = (x-3)(x+1)
