Super simple
So he wants to be three pounds away from his ideal weight (168)
Which means he can either be 3 pounds under or 3 pounds over
So his min is 165, his max is 171
To make things simple you can first find out what 8 1/16 is. 8 1/16 is approximately 8.0625. Then find what 5 1/2 is which is 5.5. Now all you have to do is subtract 5.5 from 8.0625 (8.0625-5.5) and that should be equal to 2.5625.
The value of x is 126.87° and the value of y is 53°.
<h3>What is an obtuse and an acute angle?</h3>
An obtuse angle is an angle that is greater than 90° but lesser than 180° while an acute angle is an angle between 0-90°.
From the given information:
sin x° = 0.8
x = sin⁻¹ (0.8)
x = 53.13°
x + 53.1° = 180°
x = 180° -53.13°
x = 126.87°
If cos 127° = -cos y°,
-cos y = -0.6018
cos y = 0.6018
y = cos⁻¹ (0.6018)
y = 53°
