Find the length of AB, given that be is a median of the triangle and AC = 30.

RSB [31]

SOLUTION

Draw the diagram

a median of a triangle is a line segment joining a vertex to the midpoint of the opposite side, thus bisecting that side.

Hence

$|DB|\text{ bisect |AC|}$

SInce AC=30, Then

$\begin{gathered} AB=15,\text{ CB= 15} \\ \text{Hence} \\ |AB|=15 \end{gathered}$

Thus, from the median properties of a triangle, AB = 15

Hellp me solve this thanks

Answer:

c. 10 cm

Step-by-step explanation:

The parallel sides of trapizium are the bases so

base 1(B1) =9cm , base(B2)= 12cm

$area(a) = 105 {cm}^{2}$

the perpendicular distance means the height so lets find the height

area of trapizium= B1 + B2 × h

2

${105cm}^{2}(the \: given \: area) = \frac{9cm(the \: given \: base) + 12cm(the \: given \: base)}{2} \times h$

${105cm}^{2} = \frac{21cm}{2} \times h$

now we crisscross

${105cm}^{2} \times 2 = 21cm \times h$

${210cm}^{2} = 21cm \times h$

$\frac{ {210cm}^{2} }{21cm} = \frac{21cm \: }{21cm} \times h$

h = 10 cm

hope u like it ‍❤️‍‍❤️‍‍❤️‍

Help i do not understand due before 8. o clock today!!

Hello

The equation to find the volume of a cube is a^3 Our a is 4, which means that our equation is 4^3 4 to the power of 3 is 64, which gives us our volume.

Lastly we must do 64x3,which gives us 192. This means the third box has a volume of 192in^3.

I HOPE THIS HELPS & GOOD LUCK!!! <3
