Ok why’s the picture upside down??.?
Answer:
The angle next to angle 1 is 180-58-39=83. Due to vertical angles, angle 2 is 83 degrees. So angle 3 is 180-35-83=62
Multiply the coefficients -5 and 3 which gives you -15
Then multiply variables. So x^(2+1) and it gives you x^3. Then y^(3+2) and it gives you y^5.
The final answer is -15x^3y^5
