Answer: 16,17,18
Step-by-step explanation: 16,17,18 are consecutive numbers and when you add them up the equal 51
z° = 80° (Being corresponding angles)
y° + 80° = 180° (Being linear pair of angles)
=> y° = 180° - 80°
=> y° = 100°
x° = y° (Being interior opposite angles)
=> x° = 100°
All Triangles are equal to 180° on a plane surface no triangle is equal to 180° on a curved surface.
Answer:
x ≈ 11.7
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos26° = 
= 
( multiply both sides by 13 )
13 × cos26° = x , then
x ≈ 11.7 ( to the nearest tenth )
Subtract it and you will find your answer hope this helps
