Answer:
Write each answer in centimeters.
Step-by-step explanation:
We cant help you online with measuring, although you can pull out a ruler a measure to the nearest centimeter.
First, add 20 and 40. that gives you 60. then, you divide- 420/60. that gives you 7. then multiply 7 by 20, giving you 140, and multiply 7 by 40, giving you 280. then subtract: 280-140
answer: 140
E
Because if you do the math
Answer:
3/2 =x
Step-by-step explanation:
These two angles are interior angles. They add up to 180 degrees
20x+5 = 24x-1
Subtract 20x from each side
20x-20x+5 = 24x-20x-1
5 = 4x-1
Add 1 to each side
5+1 =4x-1+1
6 =4x
Divide by 4
6/4 = 4x/4
3/2 =x
I’m pretty sure you just use pythag for that so 1.5^2 + h^2 = 2.5^2 and once you solve that you should have your answer and don’t forget to root it after
