alina1380 [7]

Answer:

1060

Step-by-step explanation:

Given:

No. of boys = 870

No. of girls = 800

Probability that a boy chosen studies Spanish = \dfrac{2}{3}

Probability that a girl chosen studies Spanish = \dfrac{3}{5}

the number of boys in the school who study Spanish :

\dfrac{2}{3}\times 870=290\times 2=580

the number of girls in the school who study Spanish :

\dfrac{3}{5}\times 800 \\=3\times 160\\\\=480

Therefore, total number of students who study Spanish would be :

480+580=1060

Given: triangle ABC,
Andrei [34K]

The value of AD in triangle ABC is approximately 9 cm.

BC = 6cm

Using trigonometric ratio for triangle CBD

sin 60° = opposite / hypotenuse

0.86602540378  =  DC / 6

cross multiply

DC = 6 × 0.86602540378

DC = 5.19615242271

DC = 5.20 cm

Let's find side AD as follows:

tan 60° = AD / adjacent

AD = 5.20 × tan 60°

AD = 9.00666419936

AD ≈ 9 cm
