From the figure,
(19x+3) =( 11x-2) + (9x+1)______{ exterior angle of a triangle is equal
to the sum of 2 opposite interior angles}
now,
19x+3 = 11x-2 + 9x+1
19x-20x = -2+1-3
-x = - 4
therefore,
X = 4.
if you want to find the value of angles ,
just put 4 Inthe place of X.
and do ..

Answer
50mph
Step-by-step explanation:
rt=d use the rate times time equals distance method.
it gives us the time=4, use an exponent to represent the rate(since that's the information we don't have equals 200km
x times 4 = 200km
4x = 200km
divide by 4 to leave the exponent by itself
x = 50km
// I AM NOT SURE, IF SOMEONE SEES THIS AND ITS WRONG CORRECT ME DIRECTLY.
hmm.. never heard of properties but take a look at this :D
X = ( 10x + 2x)
That is saying he only refilled once
