The sine of one acute angle is equal to the cosine of another when their sum is 90°.
.. (2β +10°) +(3β -25°) = 90°
.. 5β -15° = 90°
.. 5β = 105°
.. β = 21°
Then your equation becomes
.. sin(52°) = cos(38°)
The answer to the squence is either d or a i believe
Not sure about the others but
b) 8,192
the pattern is multiplying by 8 each time for b
Answer:
<em>32ft³</em>
Step-by-step explanation:
Let the shape of the locker be cubic in nature.
Volume of a cube = L³
L is the side length of one of the lockers
Volume of four lockers = 4L³
If one side of the locker is 2feet long, then L = 2ft
Substitute into the formula;
Volume of four lockers = 4(2)³
Volume of four lockers = 4(8)
Volume of four lockers = 32ft³
<em>Hence the total volume of all four lockers is 32ft³</em>
