If we're only counting 5 vowels (A, E, I, O, U) and 20 consonants (everything else, minus T), then there are
ways of picking the vowels, and
ways of picking the consonants.
We want the word to start with T, and we'll allow any arrangement of the other 4 letters, so that the total number of words is
Keep in mind that this means words like TRIES and TIRES are treated as different.
Answer:
C
Step-by-step explanation:
To make it easy let's start by organizing our information :
What do you think of when you hear a right triangle ?
AC and BD are khown so let's focus on them .
If we concentrated we can notice that AB and BD are cossing each other in the midpoints . why ?
Simply because they are the diagonals of a rhombus .
ow let's apply the pythagorian theorem :
Now we khow that : AB=BC=CD=AD=
This isn't enough . Let's try to figure out a way to calculate the length of KL wich is the base of the triangle
I smell something . yes! Thales theorem
Now we have the length of the base kl
Now the big boss the height :
What I want to do is to apply the pythgorian thaorem to khow the lenght of that small part that is not a part of the height of the triangle . I will call it D
now the height of the trigle is H= BD-D= 8-2=6
NOw the area of the triangle is :
THE ANSWER IS 18 SQ.UN
