Q2. OPTION A

Q3. OPTION B

Answer 2

Answer: Option B is the right answer

Step-by-step explanation:

• Because the three alphabets a,c and e are there in {a,b,c,d,e,f,g,h} but in option Dand C there is I which is not there in {a,b,c,d,e,f,g,h,}

• If a transversal intersects two Parallel Lines ,

if the measure of one of the angles is 40 degree

then to find the measure of its corresponding

angle

As we know that < ELB = < ALM [ vertically opposite angles]

< ELB = < ALM = 40°

< ELB = < LMD [ corresponding angles]

< ELB = < LMD = 40°

< LMD = < CMF [ vertically opposite angles]

< LMD = < CMF = 40°

< BLM + < LMD = 180°

<BLM = 140°

<BLM = 140° = <DMF [ corresponding angles]

<DMF = 140° = <CML [ vertically opposite angles]

<BLM = 140° = <ALE[ vertically opposite angles]

Thus one can calculate all the angles of transversal intersects two Parallel Lines, if one of the angles is given.

• The polynomial in coefficient form is (2,5,12)

• As we know the sum of two corresponding angles is always 180  ∘  . One angle is given as 50∘ , if another angle is x then x=50  o because corresponding angles are equal.
