If the perimeters are equal, you can form an equation to find x:
x + x + 12 + x + x + 12 = x + 11 + x + 11 + x + 16
4x + 24 = 3x + 38
- 3x
x + 24 = 38
- 24
x = 14
Now you can substitute the x value into the perimeter:
(4 × 14) + 24
56 + 24 = 80 cm
(3 × 14) + 38
42 + 38 = 80 cm
So the perimeter would be 80 cm.
I hope this helps!
Answer:
∠ B ≈ 66.42°
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos B =
=
=
, thus
B =
(
) ≈ 66.42° ( to the nearest hundredth )
For this case we have the following function:

We change the variables:

From here, we clear the value of y.

Then, we make the following change:

Finally, the inverse function is:

Answer:
The inverse of the given relation is:

Answer:
1 is to 2 is the answer. U.got that
10 10 10 1 is 31 split into three tens and one one. I'm guessing this is what you meant.
