Answer:
y = 20°
x = 35°
Explanation:
Equation's:
1) 2y + x + 105° = 180°
2) 3x + x + 2y = 180°
Make y subject in equation 2
3x + x + 2y = 180
4x + 2y = 180
2y = 180 - 4x
y = 90 - 2x
Insert this into equation 1
2(90 - 2x) + x + 105° = 180°
180 - 4x + x + 105 = 180
-3x = -105
x = 35°
Find value of y
y = 90 - 2x
y = 90 - 2(35)
y = 20°
Answer:
x-coordinate = 0
Step-by-step explanation:
In a coordinate plan there are two perpendicular lines one is x-axis and another is y-axis
x-axis is a horizontal line and y-axis is a vertical line.
Both lines intersect each other at (0,0).
On x-axis, y-coordinate remains same , i.e., y=0.
On y-axis, x-coordinate remains same , i.e., x=0.
Therefore, the x co-ordinate of any point lying on the y axis is 0.
Answer:
Step-by-step explanation:
A man steps out of a plane at 4,000m of height above the ground.The point at which he jumps out of the plane would make a good reference point. However, if his acceleration is going to change as a result of him opening his parachute 2000m above the ground, a good reference point would be there. Keep in mind though, that his velocity at that instant would need to be known for it to be useful- otherwise the airplane reference point would be just as good with appropriate modeling....
It is given in the first sentence that Ms M does fitness training for one and a half hours a day.
Hence she spends 90 minutes a day in fitness training.
