You forgot to include the options. This might help, though.
Answer:
3/10
Step-by-step explanation:
Newton Equations are such as Force = Mass * Acceleration, Potential Energy= mass * acceleration of gravity* height, Force of gravity= universal gravitational constant(Mass of the earth* Mass of Object)/( Distance in between)^2, Kinetic Energy= 1/2Mass (velocity) ^2, Momentum = speed * Mass and Voltage= current * resistance, Energy= Mass * (speed of light)^2 and etc, yet all of these are models for solving physics and mathematics problems.
OK. I used my calculator to evaluate sec(85 degrees).
My calculator doesn't have a "sec" button on it.
But I remembered that
sec of an angle = 1 / (cosine of the same angle) .
So I used my calculator to find cos(85), and then I hit the
" 1/x " key, and got 11.474, which I knew to be sec(85).
