Answer:
Step-by-step explanation:
- The two given angles are complementary, it means they add to 90°
<u>Find x:</u>
- 2x + 10 + x + 8 = 90
- 3x + 18 = 90
- 3x = 72
- x = 24
<u>Find Y:</u>
- m∠Y = x + 8 = 24 + 8 = 32°

Answer: Spherical
Step-by-step explanation:
A non -Euclidean geometry is a geometry without a flat surface, unlike the properties of things geometry’s like points, lines, and other shapes which exist in a non-flat world. Spherical geometry which is a kind of plane geometry wound round a surface of a sphere is a perfect example of a non-Euclidean geometry. Which was created by Riemann's negation.
