Answer:
∠1 = 48°
∠2 = 132°
∠3 = 48°
Step-by-step explanation:
∠1 = (360-132-132)/2 = 48°
∠2 = 132° because it is the alternate angle to 132°
∠3 = 48° because it is the alternate angle to ∠1
Answer:
I think you move the 12 to the other side.. sorry if im wrong
Step-by-step explanation:
Answer:
1.-
a) θ = 45 ° + 360k
θ = 135° + 360k
b) θ = 45 ° 0 ≤ θ < 360°
θ = 135°
2.-
a) θ = 30° + 360k
θ = 330° + 360k
b) θ = 30° 0 ≤ θ < 360°
θ = 330°
3.-
a) θ = 60° + 360k
θ = 240° + 360k
b) θ = 60° 0 ≤ θ < 360°
θ = 240°
Step-by-step explanation:
1) 2 sin θ = √2
sin θ = √2/2
1.a ) θ = 45 ° + 360k
θ = 135° + 360k
1.b) θ = 45 ° 0 ≤ θ < 360°
θ = 135°
2.
2 cos θ - √3 = 0
2 cos θ = √3
cos θ = √3/2
2.a θ = 30° + 360k
θ = 330° + 360k
2.b θ = 30° 0 ≤ θ < 360°
θ = 330°
3.- √3 cot θ - 1 = 0
√3 cot θ = 1
cot θ = 1 /√3
3.a θ = 60° + 360k
θ = 240° + 360k
3.b θ = 60° 0 ≤ θ < 360°
θ = 240°
