Answer:
Step-by-step explanation:
start with 35 and add 1 repeatedly.
P = 2L + 2W ....subtract 2L from both sides
P - 2L = 2W ...divide both sides by 2
(P - 2L) / 2 = W .....can also be written like (P/2) - L = W
Density = mass / volume
density = 20/5 = 4 g/cm^3
The interior angles of this triangle MUST add up to 180 degrees:
(180 - 125) + (180 - 75) + x = 180
Then 180 - 125 + 180 - 75 + x = 180, or
-125 + 105 + x = 0, or x= 20 degrees
