What is the value of x?

enter your answer in the box.

x =

The value of x is 25.

Step-by-step explanation:

Given:

side AB =

side BC =

side AC =

In Δ ABC is an equilateral triangle.

In equilateral triangle all three angles are same and also the sides are same.

Hence side AB = side BC

Substituting the values for side AB and side BC we get,

Hence the value of x = 25.

The value of x for the given figure is 95 And 1.67

Step-by-step explanation:

From Given figure :

Sin angle =

or ,  Sin C =  

Cos angle =  

or ,  Cos C =  

Or, Cos c =

Or, =

or, = 1 -

= 1- ( )

Or, 4x²+400+80x = - 9x² -25 +30x

or, 4x²+400+80x = 7 x² + 875 -210x

or, 3 x² + 475 -290 x = 0

Or, Solving the equation

3 x² - 285 x - 5 x + 475 = 0

or, 3 x ( x - 95 ) - 5 ( x - 95 ) = 0

or, ( x - 95 ) ( 3 x - 5 ) = 0

∴ x = 95  and x = 1.67

Hence The value of x for the given figure is 95 And 1.67  Answer
