Find the tan A and sin B exactly.

Rudik [331]

Answer:

B - tan A = 4/3, sin B = 3/5

Step-by-step explanation:

First, lets find the length of the third side

b = √15² - 12² = √225 - 144 = √81 = 9

Now, lets get Tan A and Sin B

Tan A = 12/9 = 4/3
Sin B = 9/15= 3/5

Correct option is B

SEE IMAGE! Which of the following expressions is equal to the value of x?

Virty [35]

Answer:

A) 0.9(sin50)

Step-by-step explanation:

Since this is a right triangle, we can use

sin a = opposite side/ hypotenuse

sin 50 = x /.9

Multiply each side by .9

.9 * sin 50 = x/.9 * .9

.9 (sin 50) = x

Solve for x: 0⁰ < x< 360⁰ <img src="https://tex.z-dn.net/?f=1%20%2B%205%20%5Csin%28x%20-%2010%20%7B0%7D%5E%7B0%7D%20%29

Answer:

x = 88.463°

Step-by-step explanation:

We are given a trigonometric equation and we need to find out the value of x. The angle x lies between 0° and 360° . That is ,

$\rm\implies\red{ 0^0 < x < 360^0 }$

Given trigonometric equation :-

$\rm\implies\red{ 1 + 5 sin (x-100^0)=0 }$

Subtracting 1 both sides , we have ,

$\rm\implies 5sin( x - 100^0)= -1$

Divide both sides by 5 ,

$\rm\implies sin( x - 100^0)= \dfrac{-1}{5}$

This equation can be written as ,

$\rm\implies x - 100^0 =sin^{-1}\bigg(\dfrac{ -1}{5}\bigg) \\\\\rm\implies x - 100^0 = -11.53^0 \\\\\rm\implies x = 100^0-11.53^0\\\\\rm\implies\boxed{\bf x = 88.463^0}$
