If the sine of an angle is 4/7 what is the cosine of its complement.

0.57

Explanation:

Let's begin by explaining that two angles are complementary when they sum is :

Having this clear, let's find from the following trigonometric function:

Now that we have the value of , let's find :

This is the complement of angle

Then, the cosine of the complement is:

This is the answer

heat the gas and measure the pressure

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
