What is number 5???!!

vagabundo [1.1K]

The value of m∠M is 112°

Step-by-step explanation:

In the parallelogram NPMQ, opposite angles ∠P=∠M.

To get the value of the angles, equate the two expressions;

(6x-2)°=(4x+36)°

6x-2=4x+36 ------ collect like terms

6x-4x=36+2

2x=38

x=38/2 =19

So, ∠M= (6x-2)° = (6×19 - 2)° = 112°

Which number is rational?

ziro4ka [17]

Answer:

We need some numbers to work with to truly answer this. However here's a definition of a rational numbers

A rational number is any number that isn't infinite and non-repeating. So decimals, fractions, repeating numbers/decimals like 1.535353.... (53 is the "pattern") are all rational and fair game. Numbers like pi (π), "imperfect" square roots, etc. that don't repeat and are infinite or NOT RATIONAL.

Hope this helps and have a nice day!
