Answer:

110 and 70

Step-by-step explanation:

opposite sides of parallelograms are equal so you can set 2x+30 equal to 5x-90

when you do this:

2x+30=5x-90

-2x -2x

30=3x-90

+90 +90

120=3x

/3 /3

40=x

now you can plug 40 in for 5x-90

example:

5(40)-90

200-90

110

m<r=110

<r and <s are supplementary because they are consecutive angles

supplementary is when two angles add up to 180

since <r is 110, do 180-110 and get 70

m<s = 70

Step-by-step explanation:

a^2+b^2 = c^2

C is the biggest number, so put in all the numbers in the equation then if it's equal then it's a right triangle.

example: 6^2 + 8^2 = 10^2

36 + 64 = 100

100 = 100

this one is a right angle because the two sides is equal to the hypotenuse(largest number).

Vsevolod [243]

Answer:

Area or parallelogram = base * height

Area = 9 units * 2/3 units

Area = 9/1 * 2/3 square units

Area = 18/3 square units

Area = 6 square units

Answer: area = 6 square units

Two cars, 540 kilometers apart, begin driving toward each other on a long, straight highway. one car travels 75 kilometers pe

Elodia [21]

One car travels at a speed of 75 kilometers per hour and the other car travels at a speed of 105 kilometers per hour.

Since both the cars are travelling towards each other their combined speed will be: 75+105=180 km/h.

Now, since the distance between the cars to start with is 540 km. Therefore, the time taken before the cars collide is:

$t=\frac{540}{180} =3$ hours.

Now, the speed of the canary is 100 km/h.

Therefore, the Canary flies flies for (100 km/h)x(3 hours) = 300 km before the cars collide.
