Answer:
tan 5π/24.
Step-by-step explanation:
We use the identity:
tan (A - B) = (tan A - tan B) / (1 + tan A tan B)
so the first expression simplifies to
tan ( π/3 - π/8)
= tan 5π/24.
Step-by-step explanation:
15=2c+7
15-7=2c
8=2c
8/2=c
4=c
c=4
Answer:
Step-by-step explanation:
We have the statement AB turns clockwise to coincide with BC.
= ABD + DBC
= 33.3° + 30.6°
= 63.9°
Now we have the statement a point E is drawn directly opposite point C. B, E, and C are on the same straight line
EBC is a straight line, so sum of angles =180°
ABE + ABD + DBC = 180°
ABE + 33.3° + 30.6° = 180°
ABE + 63.9° = 180°
ABE = 180 - 63.1
ABE = 116.9° ....
