A triangle is a three-sided polygon. The sum of angles in a triangle is 180 degrees.
<em><u>Types of triangles </u></em>
- An equilateral triangle : the three sides are equal in length.
- An isosceles triangle : two sides are equal in length
- A right angled triangle : an angle measures 90 degrees
The perimeter of a triangle is (8t -7 + u) centimeters
The perimeter of a triangle is the sum of the three lengths of the triangle
2t +2 + 6t - 7 + u -2
Combine similar terms
(2t + 6t) + (2 - 7 - 2) + u
Add combined similar terms
8t -7 + u

Answer: 4.98
Explanation: a1 is the number that is in front of the parenthesis. R is the number inside the parenthesis. N is the number you are trying to find. This is usually located on top of the sigma. Plug this all in a calculator, and you should get this answer.
Hope this helps!!!
Given:
Vertices of △XYZ are X(-4,6), Y(6,1) and Z(1,1).
To find:
The vertices of ∆X′Y′Z′.
Solution:
According to the question, △XYZ is translated 3 units up to form the image ∆X′Y′Z′, so rule of translation is defined as

Now,


Similarly,


and,


Therefore,
