Answer:
60
Step-by-step explanation:
if the opposite of <1 is 120 and the line it is sitting on is flat, we can figure out that both connected would be 180
the equation would be 180-120=60
hope this helped
Yes it is right because you are measuring by either the base to height or length times width
This is how I would solve it:
1st # = x 4(x+1)=3x+18
2nd # = x+1 4x+4=3x+18
4x=3x+14
x=14
To check: 15x4=60; 60-42=18. <u>1st # = 14; 2nd # = 15.</u>
