Answer:

AC ≈ 12.9 cm

Step-by-step explanation:

Using the ratio

sin40° = \frac{b}{20}

Multiply both sides by 20

20 × sin40° = b, hence

AC = b = 20 × sin40° ≈ 12.9

(b-c)3 +(c-d) raise to3 3+(d-b)3
Juliette [100K]

Answer:3 b − 2 c− d , t o 3 , 3 + 3d − 3 b

Step-by-step explanation:

( b − c ) ⋅ 3 + ( c -d )  raise  t o  3   3 + ( d − b ) ⋅ 3

Write the problem as a mathematical expression.

( b − c ) ⋅ 3 +( c − d )  raise  t o3   3+ ( d − b) ⋅ 3

Remove parentheses.

( b − c) ⋅ 3 + c − d , t o 3 , 3 + ( d − b ) ⋅ 3

Simplify each term.

Apply the distributive property.

b ⋅ 3 − c ⋅ 3 + c− d

Move  3  to the left of  b . 3 ⋅ b − c ⋅ 3 + c − d

Multiply  3  by  − 1  ⋅ 3 b − 3 c + c − d

Add  − 3 c  and  c. 3 b − 2 c − d , t o 3 , 3 + ( d − b ) ⋅ 3

Simplify each term.

Apply the distributive property.

3 + d  ⋅ 3 − b  ⋅ 3

Move  3  to the left of  d . 3 + 3 ⋅ d − b ⋅ 3

Multiply  3  by  − 1 . 3 + 3 d − 3 b
