How do you find the x value of an angle​
I am Lyosha [343]

Answer:

Since the value of all angles within a triangle must equal 180 degrees, if you know at least two angles, you can subtract them from 180 to find the missing third angle. If you are working with equilateral triangles, divide 180 by three to find the value of X.

Step-by-step explanation:

I hope this helps you.

Guys plsss i need help. It needs work too
Ghella [55]

Answer:

f(x+h)=x^2+2xh+h^2+2x+2h

Option D is correct option.

Step-by-step explanation:

We are given: f(x)=x^2+2x

We need to find f(x+h)

For finding f(x+h) we need to replace x by x+h

f(x+h)=(x+h)^2+2(x+h)\\We \ know \ (a+b)^2=a^2+2ab+b^2\\f(x+h)=x^2+2xh+h^2+2x+2h

Finding f(x+h) we get:

f(x+h)=x^2+2xh+h^2+2x+2h

Option D is correct option.

HELP ASSAPP WITH THIS QUESTION
Reil [10]
Okay. The prices are definitely not the same. At the Snack Shop, granola bars cost $1.25 and granola bars cost $1.30 at Sports Field. By looking at the tenths place, you can tell that 1.25 < 1.30, because 2 is less than 3. So the Snack Shop sells granola bars at a lower price. The answer is C: Snack Shop.
