Answer:
Find the reciprocal of the divisor
Reciprocal of
15/7 : 7/15
Now, multiply it with the dividend
So, 10/ 21 ÷ 15/7 = 10/21 × 7/15
= 10 × 7/ 21 × 15 = 70/ 315
After reducing the fraction, the answer is
2/9
There will be a vertical stretch with a factor of 3.
PQS would be set equal to SQR
PQS equals 45 degrees and QS bisects PQR
so therefore 45+45 would have to equal 90, since half of 90 is 45
