Answer:
x = 4, angle of sinθ,cosθ,tanθ are 29.7°
Step-by-step explanation:
Using Pythogaras' Theorem:
x² = (√65)²-7²
= 16
x = √16
= 4
sinθ = opposite/hypotenuse
θ = 4/√65
θ = sin^-1(4/√65)
θ = 29.7°
cos θ = adjacent/hypo
θ = 7/√65
θ = cos^-1(7/√65)
θ = 29.7°
tan θ = oppo/adj
θ = 4/7
θ = tan^-1(4/7)
θ = 29.7°
