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
<em>To solve for a variable, you have to isolate that variable onto one side.</em>
<h3>1.</h3>Firstly, multiply both sides by 2:
Next, divide both sides by a + b and <u>your answer will be: </u>
For this, divide both sides by πr², and <u>your answer will be </u>
Firstly, subtract both sides by 2πr²:
Lastly, divide both sides by 2πr, and <u>your answer will be: </u>
