Answer:
Explanation:
Remove parentheses.
Group like terms.
Add/Subtract the numbers: 4 - 7 + 73 = 70
Subtract 8y from both sides.
Simplify.
Subtract 70 from both sides.
Divide both sides by 6.
x = 5
Since you hace an isoceles triangle angle A is equal to angle C. So angle C is also 73°. All triangles have an internal sum of 180. So you can solve the following equation
180 - 73 - 73 = 6x + 4
34 = 6x + 4
34 - 4 = 6x
30 = 6x
x = 30 / 6
