I see this triangle is isosceles.  Thus, it has 2 sides of length 8 and 2 angles of measure 30 degrees.

(30 deg) + (30 deg) + (angle A) MUST add up to 180 degrees.

Thus, 60 deg + Angle A = 180 deg, so that Angle A = (180 - 60) deg, or 120 deg (answer)

How do you simplify the expression “3x (2/x + 5) +4”?
Bas_tet [7]

Answer:

15x + 10

Step-by-step explanation:

distribute the 3x to the 2/x and 5 inside the parentheses:

3x(2/x) + 3x(5) + 4

multiply:

6x/x + 15x +4

There is x in the numerator and the denominator of 6x/x, so the xs cancel:

6 + 15x + 4

15x + 10

Find the inverse of the function y = x2 – 12
harkovskaia [24]

Keywords:

<em>Function, inverse of a function, variable </em>

To find the inverse of a function we must clear the value of the variable x and finally return change.

By definition we have to:

Be a function of the form y = f (x), the inverse of that function is given by:

f ^ {- 1} (y) = f ^ {- 1} (x) = x

Then we have the following function:

y = f (x)

Where f (x) = x ^ 2 - 12

We clear x:

x ^ 2 = y + 12

x = \pm\sqrt {y + 12}

Returning the change we have:

f ^ {- 1} (x) = \pm\sqrt {x + 12}

Answer:

The inverse function of y = x ^ 2 - 12is f ^ {- 1} (x) = \pm\sqrt {x + 12}
