Angle rst is a right angle. angle rsu has a measure of 25°. what is the measure of angle tsu? 25° 45° 65° 75°

65°

Explanation:

In any triangle, the sum of the three internal angles makes 180°.

In this problem, we have a right triangle, which means that one angle is 90°. We are also told that another angle is 25°, so if we call x the unknown angle, we must have:

90° + 25° + x = 180°

Re-arranging the equation, we can solve to find the value of x:

x = 180° - 90° - 25° = 65°

answer: he got 23

explanation:

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.
