1. You have the following information:

 Sinx=5/13

 Cosx=12/13

 2. By definiton, you have:

 Tanx=(Senx)/(Cosx)

 3. When you susbtitute Senx=5/13 and Cosx=12/13 into Tanx=(Senx)/(Cosx), you obtain:

 Tanx=(Senx)/(Cosx)
 Tanx=(5/13)/(12/13)
 Tanx=(5)(13)/(13)(12)
 Tanx=65/156

 4. Therefore, the answer is;

 Tanx=65/156

Find the value of each variable.​
insens350 [35]

Step-by-step explanation:

11)

x= 5

{y}^{2}  = 2 \times  {5}^{2}  \\  {y}^{2}  = 50 \\ y = 5 \sqrt{2}

12)

\tan(30 )  =  \frac{9}{y}  \\ y =  \frac{9}{ \tan(30) }  = 9 \sqrt{3}  \\  {x}^{2}  =  {9}^{2}  +  {(9 \sqrt{3} )}^{2}  \\  {x}^{2}  = 324 \\ x = 18

13)

\sin(60)  =  \frac{x}{22}  \\ x = 11 \sqrt{3}  \\  \cos(60)  =  \frac{y}{22}  \\ y = 11

14)

{16}^{2}  =  {x}^{2}  +  {y}^{2}  \\ x = y \\  {16}^{2}  = 2 {x}^{2}  \\ x = 8 \sqrt{2}  \\ y = 8 \sqrt{2}

15)

\tan(30)  =  \frac{x}{42}  \\ x = 14 \sqrt{3}  \\   \cos(30)  = \frac{42}{y}  \\ y =  \frac{42}{ \cos(30) }  \\ y = 28 \sqrt{3}

16)

{(19 \sqrt{2}) }^{2}  =  {x}^{2}  +  {y}^{2}  \\ x = y \\ 722 = 2 {x}^{2}  \\  {x}^{2}  = 361 \\ x = 19 \\ y = 19

A right triangle ABC with height AB labeled 3 units and base BC labeled 5 units is shown. The area of the triangle above will eq
zhenek [66]

Answer:

Step-by-step explanation:

Answer:

w=3

Step-by-step explanation:

The area of the triangle is given by

A = 1/2 bh

the base is 5 and the height is 3

A = 1/2 (3) * 5 = 15/2  units ^2

The area of a rectangle is

A = l*w

A = 5w

The area of the triangle = 1/2 the area of the rectangle

15/2 = 1/2 *5w

15/2 = 5/2 w

Multiply each side by 2/5 to isolate w

2/5 * 15/2 = 2/5 *5/2 w

3 =w
