How many liters are in 1 dekaliter? use the metric table to answer the question.

There are 10 liters in one dekaliter.
Hope this helps! :)

In the first triangle 80+20+p=180 (since sum of all angles of a triangle is 180)so p= 80also in second triangle 55+45+q=180 (since sum of all angles of a triangle is 180)so q=80so we can conclude that p=80 degrees q=80 degrees so p=q=80 degreeshence option b is correct
