Step-by-step explanation:</u></h3>
Each of four friends orders a sweatshirt from a catalog.
There are 15 colors of sweatshirts, 5 of which are all cotton and 10 of which are a blend.
We have to find the probability that the friend order only cotton sweatshirt:
As there are 5 cotton shirts out of which four are to be selected from a total of 15 coloured shirts.
Now we know that a probability is defined as:
Probability=( Number of favourable outcomes)/(Total number of outcomes)/( Total number of outcomes)
So, the probability is:
Hence, the probability is:
Since angle 1 and 2 are supplementary they should equal 180 degrees. So 180-67=113 and since angle 1 and 3 are vertical they are congruent so angle 3 equals 113

Answer:
B: SAS
Step-by-step explanation:
You know that QR is congruent to PS.
You also know that angle qsr and pqs are both 90 degrees.
Lastly QS is a shared side so it must be the same length.
