Find the area of the triangle. Figure is not drawn to scale. Show your work. (Image attached)

Zolol [24]

Answer: $13.8cm^2$

Step-by-step explanation:

The area of a triangle can be calculated with the formula:

$A_{(triangle)}=\frac{b*h}{2}$

The base of the triangle is "b" and the height of the triangle is "h",

In the figure you can observe that the base and the height of the triangle are:

$b=6.9cm\\h=4cm$

Knowing these values, you can substitute them into $A_{(triangle)}=\frac{b*h}{2}$ .

Therefore, the area of the triangle is:

$A_{(triangle)}=\frac{(6.9cm)(4cm)}{2}$

$A_{(triangle)}=13.8cm^2$

Figure this out please Asap.

If the polygons are similar then the sides are in proportion.

$\dfrac{32}{24}=\dfrac{32:8}{24:8}=\dfrac{4}{3}$

Therefore we have the equations:

$\dfrac{x-1}{6}=\dfrac{4}{3}\qquad\text{cross multiply}\\\\3(x-1)=(4)(6)\\\\3x-3=24\qquad\text{add 3 to both sides}\\\\3x=27\qquad\text{divide both sides by 3}\\\\\boxed{x=9}$

$\dfrac{y+1}{21}=\dfrac{4}{3}\qquad\text{cross multiply}\\\\3(y+1)=(21)(4)\\\\3y+3=84\qquad\text{subtract 3 from both sides}\\\\3y=81\qquad\text{divide both sides by 3}\\\\\boxed{y=27}$

Answer:

y = -4x +2

Step-by-step explanation:

The equation you're writing is in slope-intercept form. The coefficient of x is the slope, which is the "rise"/"run" of the line.

Here, to get from the left point to the right point, you must go down 4 units (rise=-4) and 1 unit to the right (run=1). So, the slope is ...

m = rise/run = -4/1 = -4

The constant in the equation is the y-intercept: the y-coordinate of the point where the line crosses the y-axis. That point is marked as (0, 2), so its y-coordinate is 2.

The equation for the line is ...

y = -4x +2
