Answer:
Step-by-step explanation:
If the second angle's measure is based on the first angle's measure, and the third angle's measure is also based on the first angle's measure, then the first angle is the main angle. We will call that x.
1st angle: x
2nd angle: x + 20%
3rd angle: x - 20%
By the Triangle Angle-Sum Theorem, all those angles will add up to 180, so:
x + (x + 20%) + (x - 20%) = 180 and
3x = 180 so
x = 60. That means that
2nd angle: 60 + (.2*60) which is
60 + 12 = 72 and
3rd angle: 60 - (.2*60) which is
60 - 12 = 48. Let's check those angles. If
∠1 = 60
∠2 = 72
∠3 = 48,
then ∠1 + ∠2 + ∠3 = 180 and
60 + 72 + 48 does in fact equal 180, so you're done!
Answer:

Answer:
63/90
Step-by-step explanation:
just subtract 27 from 90 and you will get 63 so jordan got 63 questions wrong out of 90 which means 63/90.
Step-by-step explanation:
the Domain of the function
=> Df ={1, 3, 5, 7, 9}
the Range of the function
=> Rf ={0, 1, 2, 3, 4}
