Find the value of x in the triangle shown below 30 points!

Since the triangle in the picture has two equal sides, we can conclude that this triangle is an isosceles triangle. Also in an isosceles triangle, the base angles are equal, and the sum of three angles in a triangle is always 180°, we have the equation:

39° . 2 + x° = 180°

=> x°           = 180° - 39° . 2

=> x°           = 180° - 78°

=> x°           = 102°

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
