Answer:
43, 40
Step-by-step explanation:
1) Exterior angles are equal.
(x + 44) = 87 --> 87 - 44 = 43
x = 43
2) Alternate interior angles are equal.
(x - 30) = 70
x = 40
Answer:
The simplified expression is 
Step-by-step explanation:
The given expression is:

Multiply the items in the numerator together ( 15b * 8 = 120 b). Also multiply the items in the denominator together ( 4 * 9a²b² = 36a²b²). The expression thus becomes:

Divide both the numerator and the denominator by 12b:

The expression finally becomes:
