Answer: 14 miles
Step-by-step explanation:
In the attached figure we can see the two segments the man drove, where the
is the distance of a road that goes from the man's home directly to his work.
It should be noted that
is also the hypotenuse of the righ triangle formed. Hence, we can use the Pithagorean theorem to find this distance:

Then:

X+20+10x=20+9x
adding like terms
x(10+1)+20=20+9x
11x+20=9x+20
subtracting 9x from both sides
2x+20=20
subtracting 20 from both sides
2x=0
dividing by two for both sides
x=0
Answer:
its 52 :b
Step-by-step explanation:
Answer:
9x + 1 = 9x + 1. . LISTEN BECAUSE WHWN 9X IS WITH BASE AND IN 1 THERE IS NO X IN 1. SO,WHEN THERE BASE ARE EQUAL THEN ONLY WE CAN CALCULATE IT.OR TO DO ANY EQUATION OF IT.
Answer:
c = 9
Step-by-step explanation:
Since angle d and 59 are on a right angle (indicated by the small square)
We can equate the sum of these angles to 90:
d+59=90
Now we subtract 59 from both sides:
d+59-59=90-59
d=31
Since angles d,c and 140 are on a straight line we can equate the sum of these 3 to 180:
c+d+140=180
Substitute d with 31 from previous working out:
c+31+140=180
Simplify:
c+171=180
Subtract 171 from both sides:
c+171-171=180-171
Simplify:
c= 9
