y = 180° - x
x = 180° - (82° + 54°) } => y = 82° + 54° = 136°
Answer:
144
Step-by-step explanation:
120 x 1.20 = 144
.20 is 20% and adding the 1 adds it to the original value
Answer:

Step-by-step explanation:
1) <u>The two points are</u>:
a) On the first swing she swings forward by 18 degrees: <em>(1, 18)</em>
b) On the second swing she only comes 13.5 degrees forward: <em>(2,13.5)</em>
2) <u>The general equation using the form given is</u>:

3) <u>Substitute the two points</u>:

4) <u>Divide the second equation by the first one</u>:
⇒ 13.5 / 18 = B
⇒ B = 0.75
5) <u>Substitue B = 0.75 into the first equation</u>:
18 = A (0.75) ⇒ A = 18 / 0.75 = 24
Hence, the equation is:

It's A because 6^4=6×6×6×6
