# The picture shows an obtuse angle because
## the opening of the angle is greater than 90o
but less than 180o.
The picture demonstrates a right angle
because the angle formed where the rays
meet measures 90o.
The picture shows congruent segments
because each side is equal in length.

Given $\frac{1}{2} a + \frac{1}{3} > \frac{3}{4}$
If we multiply all terms (both sides of the inequality) by 12 we can clear the fractions

# The product of two successive numbers is 8372. Which is the smaller between these two numbers?
A 75
B 64
C 91
D 82
Option: [C]
Let the two numbers be x and (x+1) respectively
So, x(x+1) = 8372
x2 + x - 8372 = 0
x2 + 92x - 91x -8372 = 0
(x + 92)(x - 91) = 0
x = 91
Hence the two numbers are 92 and 91 and the sm... | HuggingFaceTB/finemath | |
