Question

solve this trigonometry :-
tan 60°=CD/80-x​

Answer 1

Step-by-step explanation:

tan 60°= √3

therefore ,

√3=CD/80-x

√3(80-x)=CD

1 .73(80-x)= CD. (because √3=1.73)

138.4-1.73x=CD

Answer 2

Answer:

x= 1/80 (CD - 80√3)

Step-by-step explanation:

steps:-

1. √3 =CD/80- x

2.√3 = CD/80- x is equivalent to CD/80- x =√3: CD/80- x = √3

3. - x = - 1/80(CD)+√3

4. x = CD/80-√3
