Answer:
m<F = 79 degrees
Step-by-step explanation:
As per the given information;
m<E = 22, the triangle EDF (the one that is given in the picture) is isosceles (meaning that the sides are congruent).
In an isosceles triangle, (a triangle where the sides are congruent) the base angles (the angles opposite to the two congruent sides) are also congruent. One should also know, that in an isosceles triangle, like in any triangle, the sum of the measures of the angles equals 180 degrees.
Using this we can say that
m<D = m<F
To keep it simple while solving the problem, let's say that they have a value of x degrees.
So,
m<E + m<D + m<F =180
Subsitute
22 + x + x = 180
Simplify and inverse operations
22 + x + x = 180
-22 -22
2x = 158
/2 /2
x = 79
So the measure of <D and <F is 79 degrees.
Answer:
Hyperbola
Step-by-step explanation:
Its just like a parabola, but with 2 equal cones making them on opposite sides.
determinant: 
(a) 
D<0 means there are no real roots. there are two complex roots with imaginary components.
(b) D=16+20=36>0
D>0 means there are two real roots
(c) D = 20^2-4*4*25 = 0
D=0 means there is one real root with multiplicity 2
Answer:
The third figure is the answer (Look to the attached figure
Step-by-step explanation:
* The point of symmetry means
- If a figure or graph can be rotated 180° about a point P
and end up looking identical to the original, then P is a point
of symmetry
- The same distance from the central point
but in the opposite direction.
* Lets look to the four answers
- In the 3rd figure first line up can be rotated 180° about a point P
and end up looking identical to the second line down, then P
is a point of symmetry
- The same distance from the point p
but in the opposite direction.
* The figure show the answer
