The two angles are 155 degrees and 25 degrees
<h3><u>
Solution:</u></h3>
Given that two supplementary angles are in ratio 31 : 5
Let the first angle be 31a
Let the second angle be 5a
Two Angles are Supplementary when they add up to 180 degrees.
Therefore,
first angle + second angle = 180 degrees
<em><u>Therefore the angles are:</u></em>
first angle = 31a = 31(5) = 155 degrees
second angle = 5a = 5(5) = 25 degrees
Thus the two angles are 155 degrees and 25 degrees
Answer:
For 0° ≤ x ≤ 360° we have:
x=0, 360, arccos(1/6), -arccos(1/6)
Step-by-step explanation:
Replace cos(x) by y
6y²-7y+1=0
6y²-6y-y+1=0
6y(y-1) -(y-1)=0
(y-1)(6y-1)=0
Roots:
y=1, cos(x)=1, x=0 and 360
y=1/6, cos(x)=1/6, x=arccos(1/6) and x=-arccos(1/6)
By plunging 5 into the equation as x, you have the equation
7(5) - 15
7 * 5 = 35 so
35 - 15
f(5) = 20
Her goal is to drink 12 glasses of water, because the question tells us that every glass of water has the same amount of ounces. If she drank 6 glasses and there's 66 ounces in total, all we have to do to get the amount of ounces per glass is divide 66 by 6 to get 11. Therefore, we know that the total amount of ounces divided by the amount of ounces per glass is the amount of glasses, and 132 divided by 11 is 12.
