Answer:
(-5x2)•3=
-15x^2
no values of x make the equation true
Step-by-step explanation:
Given that her work is correct, then the final step gives
4 = 5 ← meaningless
This indicates that the equation has no solution
m∠8 + m∠7 = 180°
therefore
m∠7 = 180° - m∠8
m∠8 = 124°
substitute:
m∠7 = 180° - 124° = 56°
Answer: 56 degrees
