How do i find the unknown side length of a triangle?

Answers

By using Pythagoreans Theorem: a^2 + b^2 = c^2

several ways like somebody said below you can use use pythag assuming u know the other 2 side lengths w/ a^2+b^2=c^2
however if you do not know the other two side lengths you must use trigonometry and sohcahtoa
sin(angle)= the side length opposite the angle to be referred to as O
divided by the longest side length (hypotenuse)or the angle directly across from the 90 degree angle to be referred to as H
cos(angle) the side length adjacent (next to) the known angle to be referred to as A/H
and finally tan(angle)O/A
if you are still having trouble with this id suggest youtubing "get triggy with it" decent video that explains trig pretty well as well as how to find a missing angle rather than a side length
hope this helps -j

Which function in vertex form is equivalent to f(x) = 4 + x2 – 2x?

Answers

The question is asking us to find which function in the vertex form is equivalent to f ( x ) = 4 + x^2 - 2 x. We have to add 1 to make a squared binomial ( and also to subtract 1 ). f ( x ) = ( x^2 - 2 x + 1 ) - 1 + 4 = ( x - 1 )^2 + 3. Then we have the vertex point ( 1, 3 ). Answer: The function in vertex form is: f ( x ) = ( x - 1 ) ^2 + 3.

Answer:

Vertex form of the function will be f(x) = (x - 1)² + 3.

Step-by-step explanation:

Vertex form of a quadratic function is given by f(x) = a(x - h)² + k

where (h, k) is the vertex of the given parabola.

Now we will convert the function in the vertex form.

f(x) = x² - 2x + 1 + 3

= (x - 1)² + 3

Therefore, the vertex form of the function will be f(x) = (x - 1)² + 3

and the vertex will be (1, 3).
