She made an error in the STEP 1
she shouldnt multiply the numbers
we have
----> inequality A
The solution of the inequality A is the interval ------> [-1,∞)
-------> inequality B
The solution of the inequality B is the interval ------> (-∞,7]
The solution of the compound inequality is
[-1,∞) ∩ (-∞,7]=[-1,7]
therefore
the answer in the attached figure
Answer:
38 degrees
Step-by-step explanation:
Angle ABE is 90 degrees, and angle FBE is 52 degrees. 90-52 is 38.
