Considering the sum of the internal angles of a triangle, the measures are given as follows:
<h3>What is the sum of the internal angles of a triangle?</h3>
The sum of the internal angles of a triangle is of 180º.
In general terms, the sum of the internal angles of a polygon of n sides is given by:
S = (n - 2) x 180º.
For a triangle, n = 3, hence S = 180º.
For this problem, the three internal angles of the triangle are given as follows:
7x - 4, 4x, 73.
Hence we can solve for x applying the sum as follows:
7x - 4 + 4x + 73 = 180
11x = 111.
x = 10.09.
Hence:
A = 4x = 4 x 10.09 = 40.36º.
B = 7 x 10.09 - 4 = 66.64º.

Put X-4 to where Y is in the first equation. So;
X-4= -X-6
Then solve to find X;
Add 6 to both sides;
X+2=-X
Subtract X from both sides;
2=-X-X
2= -2X
Divide both side by -2;
-1=X
