Solve for x: tan(2x - 65)° = cot(3x + 15)
love history [14]

Answer:

x = 28

Step-by-step explanation:

\tan(2x - 65) \degree = \cot(3x  + 15)  \degree \\  \\ \tan(2x - 65)\degree = \tan \{90 \degree - (3x  + 15)\degree  \} \\  \\ (2x - 65)\degree = \{90 \degree - (3x  + 15)\degree  \} \\  \\  (2x - 65)\degree +  (3x  + 15)\degree  = 90 \degree \\  \\  (2x - 65 + 3x + 15)\degree  = 90 \degree  \\  \\ 5x  - 50 = 90 \\  \\ 5x = 90 + 50 \\  \\ 5x = 140 \\  \\ x =  \frac{140}{5}  \\  \\ x = 28

What is the volume of a sphere with a radius of nine units
vagabundo [1.1K]

The volume formula for a sphere is V=\frac{4}{3}\pi  r^3. If the radius is 9 units, we make the replacement accordingly. V=\frac{4}{3}\pi  (9)^3. 9 cubed is 729, so the formula now is V=\frac{4}{3}\pi  (729). Multiplying 729 by 4 and then dividing by 3 gives us the volume, in terms of pi, to be V=972\pi units^3
