Answer:
∠3 = 81
Step-by-step explanation:
Interior angles in a triangle add up to equal 180°
Hence, 58° + 41° + ∠3 = 180
58 + 41 = 99
99 + ∠3 = 180
* subtract 99 from each side *
99 - 99 cancels out
180 - 99 = 81
we're left with ∠3 = 81°
Answer:
14
Step-by-step explanation:
x/24=35/60
x=(24*35)/60
x=14
Hope this helps plz hit the crown :D
Second way:
35/60 divided by 5
7/12
x/24=7/12
1/2x/12 = 7/12
1/2x=7
x=14
Answer:
the equation of the axis of symmetry is ![x=8](https://tex.z-dn.net/?f=x%3D8)
Step-by-step explanation:
Recall that the equation of the axis of symmetry for a parabola with vertical branches like this one, is an equation of a vertical line that passes through the very vertex of the parabola and divides it into its two symmetric branches. Such vertical line would have therefore an expression of the form:
, being that constant the very x-coordinate of the vertex.
So we use for that the fact that the x position of the vertex of a parabola of the general form:
, is given by:
![x_{vertex}=\frac{-b}{2\,a}](https://tex.z-dn.net/?f=x_%7Bvertex%7D%3D%5Cfrac%7B-b%7D%7B2%5C%2Ca%7D)
which in our case becomes:
![x_{vertex}=\frac{-b}{2\,a} \\x_{vertex}=\frac{48}{2\,(3)} \\x_{vertex}=\frac{48}{6} \\x_{vertex}=8](https://tex.z-dn.net/?f=x_%7Bvertex%7D%3D%5Cfrac%7B-b%7D%7B2%5C%2Ca%7D%20%5C%5Cx_%7Bvertex%7D%3D%5Cfrac%7B48%7D%7B2%5C%2C%283%29%7D%20%5C%5Cx_%7Bvertex%7D%3D%5Cfrac%7B48%7D%7B6%7D%20%5C%5Cx_%7Bvertex%7D%3D8)
Then, the equation of the axis of symmetry for this parabola is:
![x=8](https://tex.z-dn.net/?f=x%3D8)
