Answer:

90

Step-by-step explanation:

The formula for a triangle is base times height then dividing it by 2

So 15 times 12 is 180 and dividing it by 2 gets you 90.

Hope this helps!

Answer:

<h3><u> 72</u> :)</h3>

Step-by-step explanation:

<h3><em><u>To find the area of a triangle, multiply the base by the height, and then divide by 2.</u></em><em> The division by 2 comes from the fact that a parallelogram can be divided into 2 triangles.</em> <em><u>For example, in the diagram to the left, the area of each triangle is equal to one-half the area of the parallelogram.</u></em></h3>

Hope this helps

Find the values of x any y.

Ede4ka [16]

There are so many types of angles, let's see what we've got here!

--(5x - 17) and 48 are alternate interior angles, which means that they are congruent.

--(5x - 17) and y are supplementary angles.

--48 and y are same-side interior angles, which means that they are also supplementary.

Let's solve for x first.

5x - 17 = 48

5x = 65

x = 13

Now, let's solve for y.

48 + y = 180

y = 132

Hope this helps!! :)

Write a cubic function whose graph goes through the points: (-5, 0) (1, 0) (2, -2) (4, 0)

Free_Kalibri [48]

Answer:

f(x) = $\frac{1}{7}(x+5)(x-1)(x-4)$

Step-by-step explanation:

Let the equation of the give cubic function is,

f(x) = p(x - a)(x - b)(x - c)

Here, a, b, c and d are the x-intercepts of the given graph.

Since, x-intercepts given in the graph are x = -5, 1 and 4,

Equation of the curve will be,

f(x) = p(x + 5)(x - 1)(x - 4)

Since, the graph of this function passes through (2, -2) also

-2 = p(2 + 5)(2 - 1)(2 - 4)

-2 = -p(14)

p = $\frac{2}{14}$

p = $\frac{1}{7}$

Therefore, equation will be,

f(x) = $\frac{1}{7}(x+5)(x-1)(x-4)$
