Answer:

The answer to your question is 19 in²

Step-by-step explanation:

Data

angle = Ф = 25°

hypotenuse = 10 in

Area = ?

Process

1.- Calculate the long and short legs of this triangle using trigonometric functions.

        sin Ф = Opposite side / hypotenuse

-Solve for Opposite side

        Opposite side = hypotenuse x sin Ф

-Substitution

        Opposite side = 10 x sin 25

-Result

        Opposite side = 4.22 in = short leg (height)

        cos Ф = Adjacent side / hypotenuse

-Solve for Adjacent side

        Adjacent side = hypotenuse x cosФ

-Substitution

        Adjacent side = 10 x cos 25

-Result

        Adjacent side = 9.06 in = long leg = base

2.- Calculate the area

Area = base x height / 2

-Substitution

Area = 9.06 x 4.22 / 2

-Result

Area = 19.12 in² ≈ 19 in²

marishachu [46]

Answer:

Step-by-step explanation:

We are given the following in the question:

Barlow school:

Total number of students = 873

Number of boys =

=\dfrac{4}{9}\times 873 = 388

Willow school:

Total number of students = 630

Number of girls =

=\dfrac{2}{3}\times 630 = 420

Number of boys =

Total number of students - total number of girls

=630-420 = 210

Thus, Barlow school has greater number of boys than Willow school.

Difference between the number of boys =

=388-210\\=178

Thus, there are 178 more boys in Barlow school as compared to Willow school.
