Thank you for posting your question here at brainly. The two postulate planes is the below:
1: A line contains at least two points. Postulate 1a: A plane contains at least three points not all onone line. Postulate 1b: Space contains at least four points not all on one plane. Postulate
5: If two planes intersect, then their intersection is a line.
Answer:
151283
Step-by-step explanation:
Let's make another angle y
Where y= 51° (corresponding angles )
and x+y= 180°. ( linear pair )
x+51°= 180° (y=51°)
x=180°-51°
x= 129°
<u>So the value of x is 129</u>°
Hope you got your answer !
22382. You just multiply 1178 and 19 :-)
