Hello!
You can use the Pythagorean Theorem

c is the hypotenuse which is the side across the right angle
a and b are the other sides
Put in the values you know

Square the numbers

Subtract 25 from both sides

Take the square root of both sides
a = 10.9
The answer is D) 10.9 centimeters
Hope this helps!
2x + y = 10
5x - y = 18
7x = 28
x = 4
2(4) + y = 10
8 + y = 10
y = 2

<em>Answer: B. 38 mm</em>
Step-by-step explanation:
<u>The Perimeter of a Shape</u>
The perimeter of a given shape is the sum of all exterior lengths surrounding the shape.
The figure shows a shape where all the external measures are given except the leftmost side.
This length is the sum of 3 mm + 10 mm = 13 mm.
Now calculate the perimeter:
P = 4 mm + 3 mm + 10 mm + 8 mm + 13 mm = 38 mm
Answer: B. 38 mm
