Answer:
A. 60°
Step-by-step explanation:
There's a very straight-forward explanation for this, thank god! XD
For this type of problem, there's a rule to follow for the outside angle. X and 120 should equal 180, so all you need to do is fill that gap.
180-120 = 60
60 is your answer because it completes the whole angle.
The social indicators that can be used to know the quality of life in campus are the number of hours spent in school, extra curricular activities, etc.
<h3>What are social indicators?</h3>
It should be noted that social indicators are used to monitor the social system.
The social indicators that can be used to know the quality of life in campus are the number of hours spent in school, extra curricular activities, etc. They're important to assess ones social life.

Answer:
x=75
Step-by-step explanation:
Hey There!
If you didn't know the exterior angle of a triangle is equal to the sum of the opposite interior angles of a triangle
So essentially what I'm saying is that
2x-5=70+x
step 1 add 5 to each side
-5+5 cancels out
70+5=75
now we have
2x=70+x
step 2 subtract x from each side
x-x cancels out
2x-x=x
we're left with
x=75
The vertex of this parabola is at (3,-2). When the x-value is 4, the y-value is 3: (4,3) is a point on the parabola. Let's use the standard equation of a parabola in vertex form:
y-k = a(x-h)^2, where (h,k) is the vertex (here (3,-2)) and (x,y): (4,3) is another point on the parabola. Since (3,-2) is the lowest point of the parabola, and (4,3) is thus higher up, we know that the parabola opens up.
Substituting the given info into the equation y-k = a(x-h)^2, we get:
3-[-2] = a(4-3)^2, or 5 = a(1)^2. Thus, a = 5, and the equation of the parabola is
y+2 = 5(x-3)^2 The coefficient of the x^2 term is thus 5.
