99 POINTS! If the area of the figure is 16 square centimeters, what is the height of the triangle?

erastovalidia [21]

Answer:

The height of the triangle is 3.2 cm.

Step-by-step explanation:

The area of the triangle = $16 cm^2$

Base of the triangle = 10 cm

Height of the triangle = h cm

Area of the triangle = $\frac{1}{2}\times Base\times height$

$16 cm^2=\frac{1}{2}\times 10 cm \times h$

h = 3.2 cm

The height of the triangle is 3.2 cm.

BartSMP [9]

Answer:

(x - y)(j - s).

Step-by-step explanation:

jx + sy - sx - jy

= jx - sx + sy - jy

= x(j - s) - y(j - s)

= (x - y)(j - s).
