Given:
The figure of a quadrilateral ABCD.
To find:
The perimeter of the quadrilateral ABCD.
Solution:
In an isosceles triangle, the two sides and base angles are congruent.
In triangle ABD,
[Given]
is an isosceles triangle [Base angle property]
[By definition of isosceles triangles]
...(i)
In triangle BCD,
[Given]
All interior angles of the triangle BCD are congruent, so the triangle BCD is an equilateral triangle and all sides of the triangle area equal.
[Using (i)] ...(ii)
Now, the perimeter of quadrilateral ABCD is:
Therefore, the perimeter of the quadrilateral ABCD is 35 units.
Answer:
See answer below
Step-by-step explanation:
x² - 10x + 30 = 0
x² - 10x = -30
x² - 10x + 25 = -30 +25 1/2 of the x term and square that number and add to
both side.
x² -10x + 25 = -5
(x - 5)(x - 5) = -5
=
