Sin (105) = sin (15+90)= cos 15- ℎ ℎ
Explanation:
sin(105) = sin (60+45) because sin (a +b)= sin a • cos b+ cos a• sin b
Therefore,
sin 105= sin (60+45) = sin 60• cos 45 + cos 60 • sin 45 =
The picture below is your answer.
Answer:
1. Opus - a separate composition or set of compositions by a particular composer, usually ordered by date of publication.
2. The 6 musical periods are classified as Medieval, Renaissance, Baroque, Classical, Romantic, and 20th/21st Century, with each fitting into an approximate time frame.

Explanation:
Answer: supplied air mask
Explanation: because air can go in the mask and the gases and fumes can hurt you.
The Proterozoic division of the geological time scale is an era of the Phanerozoic eon. The Proterozoic division began 2.5 billion years ago and ended 542.0 million years ago.
Explanation:
The frictional resistance of the various pipes are given by the
K value in the table which may be used with the formula
hf = KQ2
to relate the magnitude of head loss hf in the pipeline
to the volumetric flow rate, Q. Water is drawn at the constant flow
rates from the network at nodes C and D. The static heads
(elevation + pressure head) at nodes B, C and D are 100m, 65m
and 61m respectively above the local datum. Calculate the
discharges at C and D and the water level in reservoir A. (The
data has been added to the diagram to aid the solution)
Use no more than 3 iterations and 3 significant figures.
