Question

find the value of x​

Answer 1

Answer:

The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try!

And some times "x" is a wrong answer

Answer 2

Solution:-

The sum of the triangle is 180°

A/C:-

☞x+x+90°=180°

=>2x=180°-90°

=>x=90/2

=>x=45

Therefore, the value of x is 45°
