It is given in the question that B is in between C and D.
Therefore
Substituting the given values of CB,BD and CD, we will get
Combining like terms, we will get
Now we need to move 4 to the right side by adding 4 to both sides, that is
Let the number of seats of the smaller van be "x". Since it travels two times in the morning, it will be 2x. The bigger van has 14 more seats than the small one, so it will be x + 14. To find the value of x, the formula would be,
65 = 2x + x + 14
65 = 3x + 14
65 - 14 = 3x
51 = 3x
51/3 = x
17 = x
The value of x is 17.
Van A = 17 seats + 14 seats = 31 seats
Van B = 2 (17 seats) = 34 seats
Van A has 31 seats for 31 people for a single trip.
Van B has 17 seats, and since it has two trips, it can transport 34 people.
hi <3
so basically, there are a few rules you need to know of and i'll describe those first.
angles in a triangle sum to 180 degrees. AND
angles on a straight line sum to 180 degrees
so, by using the first rule, we can calculate the missing angle within the triangle:
180 - (52 + 90) = 38
now, we can use the second rule to find x
180 - 38 = 142
x = 142 degrees
hope this helps :)
Answer:
okay so i think the length of CD is 16cm
