The angle of x is 71°
Because the triangle in isosceles the two bottom angles will have the same measure.
The angles of a triangle will add to 180° so you subtract 38 and divide by 2.
You haven't shown us his answer or any of his work, so we don't know
whether it was right or wrong, and we have no way to find his mistake
if his work was wrong.
(10 discs) / (5.49 dollars) = (10/5.49) disc/dollar = 1.821 disc per dollar
(5.49 dollars) / (10 discs) = (5.49/10) dollar/disc = 0.549 dollar per disc

Answer:
it depends on what type of track, and who you are. so if its me and if its a typical quarter-mile track, it would be about a minute and 15 max. then multiply that by 20 and and yod have 25 minutes for 20 laps aka 5 miles
Step-by-step explanation:
Answer:
The solution of the given equations is (-3,2)
Step-by-step explanation:
<u>Step:1</u>
The Given equations are 2 x+3 y=0 .......(1)
x+2 y-1 =0.........(2)
<u>Step 2:-</u>
Solving<u> </u>both equations by using substitution method
multiply equation (2) with number '2' ,
2 x+4 y-2=0.......(3)
subtracting the equations (1) and (3) and cancelled 'x' terms
we get 

<u>Step 3:</u>-
substitute y= 2 in equation (1) we get




<u>Final answer</u>:-
The solution of the given equations is (-3,2)
