I think the answer should be A correct me if I’m wrong tho
Answer:
Option A is correct : . a=115, b=71
Step-by-step explanation:
Consider the attached file.
AB is parallel to CD.
∠1+ a° = 180° (since sum of linear pairs is 180°) ---(A)
And ∠1 = ∠2 because they are corresponding angles.
∠1 = ∠2 = 65°
Putting this value in (A)
⇒65°+ a° = 180°
⇒a° = 180°-65°
⇒a° = 115°
∠3+ 109° = 180°(since sum of linear pairs is 180°) ---(B)
⇒∠3 = 180°-109°
⇒∠3 = 71°
Now, ∠3 = b° (because they are corresponding angles and corresponding angles are equal)
⇒∠3= b°= 71°
Thus Option A is correct : . a=115, b=71
Answer:
m ≤ -15
Step-by-step explanation:
You can convert m into positive by multiplying -1 on both sides of the equation. This would also result to a -15.
Note that when an unknown variable changes its sign, the symbol becomes the opposite version of itself.
So,
-m ≥ 15
-m(-1) ≥ 15(-1)
m ≤ -15
Answer:
980
