Answer:
the length of the thread remaining is 790 cm
Step-by-step explanation:
Given;
original length of the thread, L₀ = 10 m = 1000 cm
the length of the thread used, L₁ = 210 cm
The length of the thread remaining is calculated as follows;
ΔL = L₀ - L₁
ΔL = 1000 cm - 210 cm
ΔL = 790 cm
Therefore, the length of the thread remaining is 790 cm

-cos²x= sin²x-1
4.sinx = sin²x-1+4
sin²x-4.sinx +3=0
(sinx-3)(sinx-1)=0
sinx≠3
sinx =1
SİN90=1
