Question

Find X. Enter a number for your answer. Do not type the symbol for degree or the word "degrees"

Answer 1

Use angle sum property (the 3 angles in a triangle sum up to 180°).

2x + x + 54 = 180

3x + 54 = 180

3x = 180 - 54

3x = 126

x = 126/3

x = 42

Answer 2

Answer:-

x = 42

Explanation:-

We know that,

Angles of a triangle adds to 180°

So,

=> 2x + x + 54 = 180

=> 3x = 180 – 54

=> 3x = 126

=> x = 126/3

=> x = 42

(x = 42° ; 2x = 84°)
