Angle x is the same as the angle opposite it so 63 degrees
angle y = 180 - 72 - 63 = 45 degrees
angle z is the same angle shown at point B so 72 degrees
The answer could be 70a+21b
58:
There are 26 letters in the alphabet and 5 of them are not consonants of the probability of not getting a consonant is 5/26
Times this by 300 to get 57.69 that rounds to 58 times a non consonant will be picked in 300 picks
It's more than 3600, so its greater than 60.
it's less than 4900, so its less than 70.
a no.'s root can end with six if the no. ends with 4 or 6.
so the no is either 64 or 66.
Now if it's 66, the square must be greater than sq of 65.
65 sq= 4225
the given no. is greater than sq of 65.
Therefore the number is 66.
