5 years because when you divide 90 by 18 to get how many years it takes the tree to grow to 90 inches tall, you get 5.
It would take him 2.5 hrs because when you divide 10 by 4 that's what you get
Answer:
Step-by-step explanation:
Total interior angles in a triangle=180 degrees
That is: 3x + 10 + 5x - 1 + x =180
9x+9=180
9x=180-9
9x=171
x=171/9
x=19
Therefore
Angle A =67 degrees
Angle B= 94 degrees
Angle C = 19 degrees
A benefit is the technology can be more aaurate and you can use a compass and a straightedge wrong and get lost. Also the compass can break
