<h2>Question:- Find the value</h2>

\frac{ \sin(20 \degree) }{ \cos(70\degree) }  +  \frac{ \cos(35\degree) }{ \sin( 65\degree)}

<h2>Answer-> </h2>

\frac{ \sin(20 \degree) }{ \cos(70\degree) }  +  \frac{ \cos(35\degree) }{ \sin( 65\degree)}

<h2>we know:- </h2>

\sin( \theta)  =  \cos(90 -  \theta)  \\  \\  \cos( \theta)  =  \sin(90 -  \theta)

So putting down the value

\frac{ \cos(90 - 20 \degree) }{ \cos(70\degree) }  +  \frac{ \sin(90 - 35\degree) }{ \sin( 65\degree)}

\frac{ \cos(70\degree) }{ \cos(70\degree) }  +  \frac{ \sin(65\degree) }{ \sin( 65\degree)}

\frac{\cancel{\cos(70\degree)}}{ \cancel{\cos(70\degree)}}  +  \frac{\cancel{\sin(65\degree)}}{\cancel{\sin( 65\degree)}}

\frac{1}{1}  +  \frac{1}{1}  \\ 1 + 1 = 2 \:  \: ans

BRAINLIESTTT ASAP!! PLEASE HELP ME :)
Andrej [43]

Answer:

2017.

Step-by-step explanation:

The equation for the future sale of motorcycles

= 5.75(1.16)^t  where t is in years

For cars it is

3.5(1.25)^t

3.5(1.25)^t > 5.75(1.16)^t

(1.25)^t > (5.75/3.5) 1.16^t

t ln 1.25 > ln 1.64286 + t ln 1.16

t ln 1.25 -  t ln 1.16 > ln 1.64286

t (ln 1.25 - ln 1.16) > ln 1.64286

t > ln 1.64286 / (ln1.25 - ln 1.16)

t > 6.64 .

So the answer is in the year 2017.

x \times  - 1 =  - x


if the integer is negetive then the product will be positive
- x \times  - 1 = x



if the integer is 0 then the product will be 0
as any no. multiplied by 0 is 0
