Answer:
Step-by-step explanation:
Given parameters:
Dimensions of the equilateral triangle = 6.2cm
Unknown:
Perimeter = ?
Solution:
The perimeter of the triangle is the sum of all its sides;
Perimeter = 3(L) for an equilateral triangle;
Perimeter = 3(6.2) = 18.6cm
to the nearest mm = 19.0cm
Hoi!
To solve this, first plug in the values for x and y.

Turns into...

Now that we've got the values plugged in, let's solve.
4 × 2 = 8


× 3 =


is your answer. :)
Answer:
98.8 cm²
Step-by-step explanation:
Hi there!
where P is the perimeter of the pentagon and a is the apothem (the line going from the center of the pentagon one edge)
<u>1) Find the perimeter</u>
where l is the side length
Plug in the side length 7.6 cm

Therefore, the perimeter of the pentagon is 38 cm.
<u>2) Find the area</u>
Plug in the perimeter (38) and the apothem (5.2)

Therefore, the area of the pentagon is 98.8 cm².
I hope this helps!
All the angles add up to 433 degrees
there’s 540 degrees in a pentagon,
540-433= 107,
there’s 180 degrees on a straight line
180-107=73
so angle a is 73 degrees
