Vertical angles are always equal. The vertical angles are the ones opposite each other. Therefore x would equal 40.
Answer:
Alcohol
Step-by-step explanation:
Alcohol would be more suitable for making measurements in a -60 degree laboratory, since its boiling point is 78 degrees and its freezing point is -80 degrees, meaning alcohol will not freeze in a -60 degree environment.
Mercury on the other hand, has a freezing point of -39. Thus, it will freeze in a -60 degree environment, making it not suitable for use in this laboratory.
For the pizza that needs 1/3 of a block you know that with 1 block you can make 3 pizzas so if each block gives you 3 pizzas and you have 9 blocks then you would show 3 x 9 = 27 so you could make 27 pizzas
for the pizzas that need 1/5 you can make 5 pizzas with 1 block so same thing
5 x 9 = 45 so 45 pizzas
To find that , divide the estimate by the actual weight and multiply by 100.
8/6*100=133.33%(rounded)
Therefore the percent error is 133.33%.
