The greater density to measure by having a mass of 2cm or 3cm
Answer:
Supplementary
Step-by-step explanation:
The two angles are completely different from each other and if you combine them together it'll form a straight line making it 180 degrees
The solution to any system graphically can be found where the 2 graphs intersect. These two graphs intersect at the point (0, 2).
Answer:
50
Step-by-step explanation:
The sum of the angles of a triangle add to 180 degrees
A + B + C = 180
2x-10 + 70+ x+30 = 180
Combine like terms
3x +90 = 180
Subtract 90 from each side
3x+90-90=180-90
3x= 90
Divide by 3
3x/3= 90/3
x=30
We want to find angle A
A = 2x-10
=2*30 -10
=60-10
50
