Answer:
12.73m
Step-by-step explanation:
using Pythagoras theorem
a = x (i change x to a for easy reference due to multiplication)
18 x 18 = a x a + a x a
324 = 2a^2
a^2 = 324 / 2= 162
a = 
= 12.7279 = 12.73 (2 decimal place)
Answer:
22.5
Step-by-step explanation:

A right triangle has one 90 angle.
The sum of the three angles of any triangle is equal to 180 degrees.
180-90= 90 degrees.
The answer is C.
