the median is the middle number in a sorted, ascending or descending, list of numbers, i like to think of it as "middle"
<span>The sum of the
angle of a triangle is 180 degrees. If you are to draw a pattern
of equilateral triangles then you know that an equilateral triangle has three equal sides. Also, its
angles are the same, having 60 degrees at each corner of the triangle. A triangle cannot qualify as an equilateral triangle if it is greater than 180 degrees or less than 180 degrees as a total angle. </span>Also if a triangle that has no two right angles, then it is called a scalene
triangle. If the triangle has two right
angles, it is called isosceles triangle. A triangle with equal sides is called
an equilateral triangle.
I believe it’s b but I’m not super sure
Answer:
Perimeter = 42 cm.
Step-by-step explanation:
The 2 legs are equal in length as it is an isosceles trapezoid.
Area of trapezoid = (h/2)(a + b) where a and b are the parallel bases.
So
(5/2) (a + b) = 45
a + b = 45 * 2/5 = 18 cm.
We are given that the length of a leg (L) is 2/3 * sum of the bases, so:
L = 2/3(a + b)
= 2/3 * 18
= 12 cm.
The perimeter = a + b + 2L
= 18 * 2*12
= 42 cm.
