Answer:
45º
Step-by-step explanation:
If the two interior angles are congruent they are the same. All angles add up to 180º, so 180-90=90. 90/2=45, ergo the answer is 45º.
There are six possible outcomes as there are six sides of the die
The answer should be 123/500
C=(1/4)*circumference
Area=pq+3.142r^2
60*3.142=pq+3.142p^2
q=((1/4)*2p*3.142)+2*3.142
q=1.571p+6.284
188.52=1.571p^2+6.284p+3.142p^2
188.52=4.713p^2+6.284p
188520=4713p^2+6284p
