Answer:
4 hours × 0.8°C = 3.2°C
temperature after 4 hours
= -2.4°C - 3.2°C
= -5.6°C
The answer would be 360 cm
Answer:
38 in
Step-by-step explanation:
P=w+w+h+h=18+18+6+6=26+12=38 in
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°)
