i don't know
the answer is c. hope we . 46 ends in the 100th place so it's just 46/100.
13 is not the same as 1/3! the division symbol is not a symbol used to connect two numbers, it is used to find their quotient. for example, 6/2 would be like saying: you have 6 cookies, and 2 friends. how many cookies does each friend get? the answer is obviously not 62, it is 3! so, the exact quotient is 0.3 repeating. you could memorize this or use the fact that 0.9 repeating is 1.
if we rotate the shape on the right 90 degrees counterclockwise we see they fit together, because they are congruent. they are exactly equal in size and shape - that's what congruent means.
so the following angles are equal in measure:
m < a = m < r
m < b = m < s
m < c = m < p
m < d = m < q.
corresponding sides are also equal in length:
sides ab = rs
bc = sp
cd = pq
ad = rq.
note: in the us the symbol ≅ is used for equality of sides. i think it means 'is congruent to'. (i'm from the uk).
