Let n be Fritzs' car speed, and n+12 be the speed of the train. Then:
1/2 (n)=1/3 (n+12)
2n+24=3n
n=24 mph
n+12=36 mph
Fritz travels 12 miles to work.
30 min @24mph=12 miles
20 min @36mph=12 miles

Answer: The angles inside a triangle are called interior angles. ... The three interior angles in a triangle will always add up to 180°. At each corner the exterior and interior angles are on a straight line, so at each corner these two angles add up to 180°.
Step-by-step explanation:
Sal proves that the angles of an equilateral triangle are all congruent (and therefore they all measure 60°), and conversely, that triangles with all congruent angles are equilateral.
X=7/3 and x=7/2
if you want the step-by-step then you just try to isolate x and it is pretty self-explanatory from there on. Hope this helped!
:P
That would be 152.24 to nearest hundredth
