The perimeter of the square is:
ft
Step-by-step explanation:
The picture is attached with the answer.
the diagonal of a square divides it into two right angled-triangles.
We can use one of the triangle to find the length of side as the diagonal will be the hypotenuse of the triangle
Let a be the side of the square, then according to Pythagoras theorem

Dividing both sides by 2

Taking Square root on both sides

Now,

Hence,
The perimeter of the square is:
ft

Answer: -43.3
Step-by-step explanation:
We will use the order of operations, sometimes called PEMDAS. <em>See attached for more information on this subject</em>.
Given:
8.7 - (1 + 3)³ + 6 · 2
Simplify parentheses:
8.7 - (4)³ + 6 · 2
Raise to the power of three:
8.7 - 64 + 6 · 2
Multiply:
8.7 - 64 + 12
Subtract:
-55.3 + 12
Add:
-43.3
Answer: -3
Step-by-step explanation:
(-1)+(-2)=-3
More than one triangle because it has to measure up to 180°
81 + 52 + 47 = 180
(Example) If you had a triangle that has the measurements 123 and 60 it would add up to be 183 so it would not be possible because the sum of all triangles cannot exceed 180°
