What is the value of x?

The answer is 40 degrees.

Step-by-step explanation:

We know that a right angle (the square on the bottom triangle) is 90 degrees. We also know that triangles always add up to 180 degrees.

90 + 50 = 140

180 - 140 = 40

So, your answer would be 40 degrees.

Hope that I helped! This was my first answer, I'm glad I could be there!

value of x = 40°

Step-by-step explanation:

here's the solution :-

we know, sum of all three interior angles of a triangle is = 180°

So,

=》x + 50° + 90° = 180°

=》x + 140° = 180°

=》x = 180° - 140°

=》x = 40°

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18
