Question

Pentagon ZEBRA is similar to pentagon

Answer 1

After performing some mathematical operations, the length of RA is 15 feet.

What are mathematical operations?

• A function in mathematics known as an operation is one that transforms zero or more input values into a clearly defined output value.
• The operation's complexity is determined by its operand count.
• The four mathematical operations are functions that take numerical inputs (i.e., inputs) and turn them into numerical outputs (i.e., another number).
• These are multiplication, division, subtraction, and addition.

So, the length of RA is:

As both the pentagons are similar, then:

• EB/IO = 13/10.4 = 1.25
• BR/ON = 18/14.4 = 1.25
• ZA/LS = 20.16 = 1.25
• EZ/IL = 22/17.6 = 1.25

Similarly,

• RA/NS = RA/12 = 1.25
• RA = 12 × 1.25 = 15 ft
  

Therefore, after performing some mathematical operations, the length of RA is 15 feet.
