recall that a circle has a total of 360°.
so that missing central angle is then 360° - 110° - 65° - 90°. Well, the arc's angle measurement is the same as the central angle they're in, so the x° is the same as 360° - 110° - 65° - 90°.
Since all triangles equal 180 degrees. You will subtract (128 + 23) from 180.
180 - 146 is 34 degrees.
x=34
Answer: Telescopes use lenses or mirrors to collect and focus waves from the electromagnetic spectrum, including visible light, allowing us to look at celestial objects. By studying the electromagnetic waves given off by objects such as stars, galaxies, and black holes, astronomers can better understand the universe.
Step-by-step explanation:
Here's how to do this problem:
6+ x= 55
-6 -6
x=49
