Answer:

C.  √16,200 feet

Step-by-step explanation:

According to Pythagorean theorem

c^2 = a^2 + b^2

Home First and Third is formed a right triangle with 2 equal sides = 90 ft

so

c^2 = 90^2 + 90^2

c^2 = 8100 + 8100

c^2 = 16,200

c = √16,200

Answer

C.  √16,200 feet

En un triángulo rectángulo A es un ángulo agudo y Sen A = 4/5 ¿Cuál será el valor de Tan A?
Nonamiya [84]

Answer:

\displaystyle \tan A=\frac{4}{3}

Step-by-step explanation:

<u>Funciones Trigonométricas</u>

La identidad principal en trigonometría es:

sen^2A+cos^2A=1

Si sabemos que A es un ángulo agudo (que mide menos de 90°), su seno y coseno son positivos.

Dado que Sen A = 4/5, calculamos el coseno:

cos^2A=1-sen^2A

Sustituyendo:

\displaystyle cos^2A=1-\left(\frac{4}{5}\right)^2

\displaystyle cos^2A=1-\frac{16}{25}

\displaystyle cos^2A=\frac{25-16}{25}

\displaystyle cos^2A=\frac{9}{25}

Tomando raíz cuadrada:

\displaystyle cos\ A=\sqrt{\frac{9}{25}}=\frac{3}{5}

La tangente se define como:

\displaystyle \tan A=\frac{sen\ A}{cos\ A}

Substituyendo:

\displaystyle \tan A=\frac{\frac{4}{5}}{\frac{3}{5}}

\displaystyle \tan A=\frac{4}{3}

PLEASE HELP
Elodia [21]

Answer:

The area of the resulting cross section is 78.5\ m^{2}

Step-by-step explanation:

we know that

The resulting cross section is a circle congruent with the circle of the base of cylinder

therefore

The area is equal to

A=\pi r^{2}

we have

\pi=3.14

r=10/2=5\ m -----> the radius is half the diameter

substitute the values

A=(3.14)(5)^{2}=78.5\ m^{2}
