Answer:

x=5

Step-by-step explanation:

First you have to solve for y. Since it is a isoceles triangle, the two base angles are equal. You dont even need to solve for y because both of them will equal 73. Now you know two of the angles are 73 degrees, 146 in total. Since you know the total degrees in a triangle is 180, set up an equation that is adding all the angles to equal 180. Then solve for x.

Solve:

73+73+(6x+4)=180

146+6x+4=180

150+6x=180

6x=30

x=5
