Answer:
60
Step-by-step explanation:
You dont have enough infor, but if its 120 degrees, A total degree of a triangle is 180, so 180-120 equals 60
Yes
Explanation replace both the x and y get the correct ans
Answer:
10
Step-by-step explanation:
Here it's given that the area of the shaded region is 48 u² and we need to find out the value of x .
The given figure is made up of two rectangles where the smaller one is inscribed into the bigger one .
- The area of shaded region will be equal to the difference of the areas of the two rectangles , that is equal to 48 u² .
- The area of rectangle is length × breadth .
- The dimensions of bigger rectangle is (x+3)(x-4) and that of smaller one is 3 × x .
So that ,
ar(bigger) - ar(smaller) = 48
[ (x+3) (x-4)] - 3(x) = 48
[ x² - 4x +3x -12 - 3x ] = 48
x² -4x -12 -48 = 0
x² - 4x - 60 = 0
x² - 10x + 4x - 60 = 0
x( x -10) +4(x -10) = 0
(x +4)(x-10) = 0
x = -4,10
- Since sides can't be negative ,
x = 10
<h3>
Hence the required answer is 10.</h3>
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.
