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°

the first american roller coaster was the mauch chunk switchback railway, built in the mountains of pennsylvania in the mid-1800s. the track, originally built to send coal to a railway, was reconfigured as a "scenic tour."
