How do you find the base of a triangle if you know the height and the area?

Well, first you have to work backward. You multiply by 2 from the area: 42*2 = 84. Now you divide 84 by 6 to get 14. That number is your missing base. To check if you are correct: 6*14 = 84/2 = 42.

Hope this helps,

If 42 is the area and the formula is bh1/2 then 42 times 2 = 6x to sold x we do 84 divided by 6 and x= 14 the height of the triangle.is 14

$g(x)=5cos((\pi )/(2)x-(3\pi )/(2))-2$

generate by: Amplitude:5 Period:4

Phase shift:(3 to the right) Vertical shift:-2

x=3,g(x)= 3

x=4,g(x)= -2

x=5,g(x)= -5

x=6,g(x)= -2

x=7,g(x)= 3

the graph is like cos(x)

How to find unknown side

Elan Coil [88]

Answer:

C = 10

Step-by-step explanation:

Find the last side of the triangle using the Pythagorean theorem.

$a^{2} +b^{2} =c^{2}$

You have a and b already, a = 6, b = 8

$6^{2} +8^{2} =c^{2} \\\\$

solve this to get

$64 + 36 = \sqrt{100}$

C = 10

Apply the same to the other 2 triangles. C is your longest side!

Identify the lateral area and the surface area of a right rectangular prism with an 8 cm by 9 cm base and a height of 13 cm.

stepan [7]

It's A: L =704cm2; S =936cm2
because your multiplying your length and width (8x9) =72
multiply 72 by the height and you get your answer for S = 936cm2
