Question

value of x pls help i cant understand this at all

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! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol.

Answer 2

Answer:

x = 17

Step-by-step explanation:

Since the triangle has 2 congruent legs then it is isosceles and the 2 base angles are congruent , that is

4x - 34 = x + 17 ( subtract x from both sides )

3x - 34 = 17 ( add 34 to both sides )

3x = 51 ( divide both sides by 3 )

x = 17
