Question

plzzzz solve it immediately

Answer 1

theta =30' in1quest . in 2 q es. 45and x=10

Answer 2

8] i) 2 sin2θ = √3
sin2θ = √3/2
sin2θ = sin 60°
2θ = 60
θ = 60/2
θ = 30

ii) tan θ = cot θ
tan θ/cot θ = 1
tan θ/1/tan θ = 1
tan^2 θ = 1
tan θ = 1
tan θ = tan 45°
θ = 45

9] i) cos(20+x) = sin 60°
cos(20+x) = √3/2
cos(20+x) = cos 30°
20+x = 30
x = 30 - 20
x = 10
