Answer:
n=9
Step-by-step explanation:
21/35 has a gcf of 7. so reduce to 3/5
move 3/5 to the left side to get
n/15=-3/5=0
solve as a linear equation.
n/15=-3/5=0 is equivalent to .67*n-0.6=0
which is equal to n=-9
Answer:
1) 45 degrees
2) 75 degrees
3) 37 degrees
4) 43 degrees
5) 137 degrees
Step-by-step explanation:
1) Angle 1 is equal to the 45 degree angle above it, so we know it is 45 degrees
2) All triangles are 180 degrees. Angle 2 = 180 - 60 - Angle 1 = 180 - 60 - 45 = 75
3) These three angles = 180 degrees. 180 - 68 - Angle 2 = 180 - 68 - 75 = 37
4) All triangles are 180 degrees. 180 - 100 - Angle 3 = 180 - 100 - 37 = 43
5) 180 - Angle 4 = 180 - 43 = 137
