Step-by-step explanation:

7(2e-1)-11=6+6e\\14e-7-11=6e+6\\14e-18=6e+6\\8e-18=6\\8e=24\\e=3

That is just one way to get to the answer, but basically just use pemdas, multiplying the parentheses and combining like terms. ;)

Describe the possible side lengths of the 3rd side of the triangle given the lengths of the 2 other sides?
Sindrei [870]
Heya !

Using a theoram about triangles ,

Given a triangle ∆ABC, the sum of the lengths of any two sides of the triangle is greater than the length of the third side ,

Also , the length of third side always greater than absolute difference of the other two sides ,

Let the third side be x ,

So , x < 9 + 8 and x > 9 - 8
x < 17 and x > 1

Hence , x ∈ [ 2 , 17 ] inch.

Above case is true for any triangle , be it scalene , Isosceles , Right-angled ...

As , for Isosceles , the third side can be 8 or 9 inches ,
For scalene , all values in the above range satusfies ,

For right angled triangle , we have 2 cases ,

Case 1 : Third side is the hypotenuse
Then , x = √(9²+8²) = √145 = 12.0415 inch.

Case 2 : Third side is not the hypotenuse
Then , x = √(9²-8²) = √17 = 4.1231 inch.

Hope it helps you ! :)

I’m really rusty with trigonometric functions
alexgriva [62]

Answer:

Step-by-step explanation:

hypotenuse is \sqrt{202\\} \\\\\\\\

because 14^2 + 3^2 = c^2

sin is = \frac{3\sqrt{202} }{202}

cos is = \frac{14\sqrt{202} }{202}

tan is \frac{3}{14}
