Answer:
1.21 kilograms
Step-by-step explanation:
Let y represent the mass of the empty basket, and x represent the mass of each ball
Create a system of equations:
3x + y = 3.64
5x + y = 5.26
Solve by elimination by multiplying the top equation by -1
-3x - y = -3.64
5x + y = 5.26
Add them together, then solve for x:
2x = 1.62
x = 0.81
Plug this back into one of the equations and solve for y:
3x + y = 3.64
3(0.81) + y = 3.64
2.43 + y = 3.64
y = 1.21
So, the mass of the empty basket is 1.21 kilograms
The 3 inside angles of a triangle need to equal 180 degrees.
You are told two of the angles are 106 and 59.
To find the 3rd angle subtract the 2 known angles from 180:
180 - 106 - 59 = 15 degrees.
The one on the left side: 180 - 33 - 114 = 33
The one on the right: 180 - 90 - 73 = 17
