Answer:
Step-by-step explanation:
Because CB = 6 cm, we can find CD
Use Triangle CDB.
<BCD = <BCA - <ACD
<BCD = ?
<BCA = 90
<ACD = 60
<BCD = 90 - 60
<BCD = 30
Cos 30 = CD / CB
CD = Cos(30) * BC
CD = 5.196 cm
<A = 90 - ACD
<ACD = 60
<A = 90 - 60
<A = 30
Sin(<A) = CB / AB
AB = CB / sin(<A)
AB = 6 / 0.5
AB = 12
Area =1/2 CD * AB
Area = 1/2 * 5.196 * 12
Area = 31.18
Answer:
42
Step-by-step explanation:
First condense all the numbers with exponents:
3² x 5³x 8 divided by 3 x 5³ x 8
27 x 125 x 8 divided by 3 x 27 x 8
Then multiply 27 , 125 ,and 8
27 x 125 x 8 =27000
Then multiply 3, 27 ,and 8
3 x 27 x 8 = 648
Then divide 27000 by 648
27000 / 648 = 41.6666666667
Which rounds to about: 42
