Answer:
m<X =
Step-by-step explanation:
From the given isosceles triangle, we have;
<W and <V as the base angles
So that,
m<W = m<V = 27 (base angles of an isosceles triangle are equal)
Thus,
m<X + m<V + m<W = 180 (sum of angles in a triangle)
m<X + 27 + 27 = 180
m<X + 54 = 180
m<X = 180 - 54
= 126
m<X =
Answer:
The coordinate of the vertex of the parabola is (h,k) = (3,20)
Step-by-step explanation:
The given equation of the parabola is
Now, the General Parabolic Equation is of the form:
, then the vertex is the point (h, k).
Now, to covert the given equation in the standard form:
Using the COMPLETE THE SQUARE METHOD,
or
⇒The general formed equation of the given parabola is
Comparing this with general form, we get
h = 3, k = 20
Hence, the coordinate of the vertex of the parabola is (h,k) = (3,20)
