22's answer is because they're alternate
51.54 rounded to the nearest whole number equals to 52.
Answer:
2nd option
Step-by-step explanation:
Express the sum of the 2 polynomials by removing the parenthesis , so
5
- 2x³ + x + 4 - 3
+ 2x³ - 5x ← collect like terms
= 9 - 3 - 4x
Option D: 140° is the right answer
Step-by-step explanation:
In the given figure, a traversal is intersecting two parallel lines.
When two parallel lines are intersected by a traversal 8 angles are formed.
Corresponding angles:
Corresponding angles have same relative position when two parallel lines are intersected by a traversal So in the given figure the corresponding angles are:
m∠1 and m∠5
m∠2 and m∠6
When two parallel lines are intersected by a traversal, the corresponding angles are equal
So,
m∠1 = m∠5
m∠5 = 140°
Hence,
Option D: 140° is the right answer
