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

How do you solve y=5/8b + 10 for b

joja [24]

Answer:

b = $\frac{8y-80}{5}$

Step-by-step explanation:

Given

y = $\frac{5}{8}$ b + 10

Multiply through by 8 to clear the fraction

8y = 5b + 80 ( subtract 80 from both sides )

8y - 80 = 5b ( divide both sides by 5 )

$\frac{8y-80}{5}$ = b
