Send . i don’t want just the answer; i would like to know how to do it.

606.36 m

Step-by-step explanation:

step 1 : find the angles of bigger triangle

The angles given are 25 degrees and 90 degrees (small box on the bottom right indicates the 90 degree angle )

step 2: Add the angles and minus it by 180 degrees ( because the total angle of every triangle is 180 degrees )

you will get the answer of 65 degrees

step 3: use sine formula ie :

a,b,c- sides of the triangle

A,B,C- angles of the triangle

label 25 degrees as B

and 390m as b( b and Bare corresponding ie diagonally opposite )

now angle labelled A you have already found which is 65 Degrees

its corresponds with the base of the triangle .( label the base to be b)

Note :disregard you will only need the first two equations from your general equation

now place the values into your equation it will look like this

now perform opposite operation

you will get the answer   836.36(round off to the second decimal)

BUT WAIT !!

that's not all you will have to subtract  230m from your answer which is 836.36m and you will get the the distance from T to H .

final answer 606.36 m

hope this help
