Chapter : Linear equations
Lesson : Math of Junior High School
2x - 3 + 3x = -28
= 5x - 3 = -28
= 5x = -28 + 3
= 5x = -25
= x = -25 / 5
= x = 5
One angle = 90°
the other 3 angles = 360 - 90 = 270
so
x + 2x + a = 270 but a = 168
3x + 168 = 270
3x = 102
x = 102/3
x = 34
answer
x = 34
Solution:
A plane is a two Dimensional figure.
The Intersection of two planes that do not coincide is always a line.
Consider two planes ,A and B, Following are the possibilities
1. They may be parallel to each other.→→→ No curve obtained
2. The planes A and B can Coincide with each other.→→→Intersection is a plane.
3. The planes A and B are intersecting.→→→→Intersection is a line.
