For #2, ∠3 and ∠1 are supplementary. You know that the measure of ∠1 is 162°, so what is ∠3? 180-162=18.
m∠3=18° if ∠1=162°.
Hope this helped!
They are dependent events because if cara spins it and it lands on her she gets to play with the puppy, But if she misses it and her brother spins and it lands on him he gets to play with the puppy.
Short answer: the event is dependent because the outcome of the first spin effects the brother outcome
I’m pretty sure it’s (x-7)(x+6)
to factor you need it to multiply to -42 and add to -1 which gives you -7 and 6
0.444444 , 0.555556 , 0.666667 , They each have a repeating decimal and so you can predict : 0.777778 , 0.888889
