Question

could someone please check if my answer is correct

Answer 1

my answer for question (a) is tan2x= - 120/119

Answer 2

tan(x)=opposite/adjacent = 12/5

Answer 3

tan2x=2tanx/1-tan^2x

Answer 4

and then i plugged the value of tanx into the equation to get -120/119

Answer 5

tan 2x= 12/5

Answer 6

could you please explain

Answer 7

ok

Answer 8

ok because there are 2 angles of x's

Answer 9

so its like saying tan(x+x)= 12/5

Answer 10

?

Answer 11

yeah there are two x angles so we will add them.

Answer 12

ok now i see. i took both angles as x

Answer 13

is your doubt clear

Answer 14

thank you :)

Answer 15

for question be i got two answers for tanx one was 0.6 and the other -1.5

Answer 16

why do we take tanx=0.6 as the answer ?@Techworm

Answer 17

(b)*

Answer 18

@Techworm

Answer 19

you know that x is in between 0 to 90. and tan x is always positive between 0 to 90 degrees

Answer 20

because its a right angled triangle

Answer 21

thanks for the explanation

Answer 22

your welcome

Answer 23

as for question c

Answer 24

can i find x by x=tan-1(30.96 degrees)

Answer 25

sorry x=tan-1(0.6)

Answer 26

I dont understand this equation. can you make it in proper format

Answer 27

tan(x)=0.6 from question (b)

Answer 28

oh you mean \[\tan^{-1} 0.6 \]

Answer 29

x=inverse tan(0.6)= 30.96 degrees

Answer 30

correct

Answer 31

is that how we find the length of AT?

Answer 32

the length of AT = y (OPPOSITE)

5 (ADJACENT)

Answer 33

tan(30.96 degrees) = y/5

Answer 34

you have got tan x = 0.6;

\[\tan x=0.6= \frac{ AT }{ GA }\]

Answer 35

i have a question arent both angles of x's have a different value?

Answer 36

\[0.6=\frac{ AT }{ 5 } \] so AT= 0.6x5 = 3

Answer 37

in the textbook the answer is 3 1/3m

Answer 38

then tan x value must be wrong

Answer 39

we took tan x = 0.6, which is wrongly calculated i guess

Answer 40

i trusted you saying that tanx = 0.6

Answer 41

yes thats what i think as well

Answer 42

i was wrong

Answer 43

the angle of 2x = 67.38 degrees

Answer 44

now you do calculations. you know how to do it .. you do it by yourself. I am leaving this problem
