How do i find he value of x and the tangent, cosine, and sine of the marked angle?

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°
