Answer:

C

Step-by-step explanation:

using Pythagoras' identity in the right triangle

the square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² + 4² = 9²

x² + 16 = 81 ( subtract 16 from both sides )

x² = 65 ( take square root of both sides )

x = \sqrt{65}

∆JKL~∆MNO and J/K MN =2/3 find the length of NO if KL=12.
Gre4nikov [31]

Answer:

Therefore the length of NO is 18 units.

Step-by-step explanation:

Given:

∆JKL~∆MNO and

\dfrac{JK}{MN}=\dfrac{2}{3}

KL = 12.

To Find :

the length of NO = ?

Solution:

Δ JKL ~ Δ LMN ….{Given)

If two triangles are similar then their sides are in proportion.  

\dfrac{JK}{MN} =\dfrac{KL}{NO}=\dfrac{JL}{MO} \textrm{corresponding sides of similar triangles are in proportion}\\  

Substituting the values we get

\dfrac{2}{3} =\dfrac{12}{NO}\\\\NO=\dfrac{36}{2}=18\\\\NO=18\ unit

Therefore the length of NO is 18 units.

Answer plz ASAP thx
Lyrx [107]

Answer:

D 540 mm cubed

Step-by-step explanation:

all you have to do is multiply the base area and the height together to get the volume. I can not see from what was given if the base area was divided by two because it is a triangle, if so this would be the anser if you not you want to divide the base area by half and then multiply it by the height to get your answer.
