Step-by-step explanation:

Step 1: Define

Identify variables

Angle θ = ?

Adjacent Leg = 13

Hypotenuse = 20

Step 2: Find Angle

Substitute in variables [cosine]: cosθ = 13/20
Inverse Trig: θ = cos⁻¹(13/20)
Evaluate: θ = 49.4584°

BRAINLIEST can someone please help!!!!!

I don't know about the first one but for the second one:

${2}^{3x + 2} - {2}^{3x} = 48 \\ \Leftrightarrow {2}^{3x} {2}^{2} - {2}^{3x} = 48 \\ \Leftrightarrow {2}^{3x} ( 4 - 1) = 48 \\ \Leftrightarrow 3 \times {2}^{3x} = 48 \\ \Leftrightarrow {2}^{3x} = 16 \\ \Leftrightarrow {2}^{3x} = {2}^{4} \\ \Leftrightarrow 3x = 4\Leftrightarrow x = \frac{4}{3}$
