Find the values of a and b. The diagram is not to scale. Its not c
OlgaM077 [116]

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

If an atom had a nucleus one foot in diameter, what would be the diameter of the atom in miles?
LiRa [457]
If we take hydrogen as an example, the size of hydrogen is about 25000 times larger than that of its proton. 1 Mile is roughly <span>5280 ft, which means that the size of the entire hydrogen atom would be </span>4.73 miles in diameter.
