Step-by-step explanation:
Using the sine and cosine ratios in the right triangle and the exact values
sin60° = and cos60° = , then
sin60° = = = = ( cross- multiply )
2BC = 10 ( divide both sides by 2 )
BC = 5
------------------------------------------------------------------------
cos60° = = = = ( cross- multiply )
2AB = 10 ( divide both sides by 2 )
AB = 5
Answer:
Step-by-step explanation:
A=bh/2
A=(1.2b)(1.2h)/2
A=1.44(bh)/2
A=0.72bh
b=10cm and h=5c
A=0.72(10)(5)
A=36 cm^2
If it is divisible by 3 and 7 then it is divisible by (3 times 7)
3 time s7=21
just do muliplyes of 21 and find which are between 364 and 384
21
42
63
...
336
357
378
399
answer is 378
