what is the remainder when 3^1000000 is divided by 14??
How this happened ?
In a Non Right Angle Triangle.
Area of a triangle is
1/2 * bc * sinA = 1/2 * ab * sinC = 1/2 * ca * sinB
My question is : if its a non right angle tirangle, how does trigonometry works ?
what will be sinA if there is no perpendicular ??
from 1-500 how many numbers are there whose digit sum is 6 ?
If circumradius of a right-angled triangle with perimeter 180 is 41, find its area.
In how many ways can we rearrange letters of the word MATHEMATICS ?? 😉
