Find the area of a triangle whose vertices have the coordinates (-1,1) (-1,5) (4,1)
Alekssandra [29.7K]

The triangle that forms is a right-angled triangle. To work out the area, you just do the base × height, all divided by 2.

Therefore, you do 5 (the base) × 4 (the height) and you get 20.

Then you divide by 2 to finish the equation and you should find that the total area of the triangle is 10 units² (20 ÷ 2 = 10).

Hope that helps :)

PLEASE HELP ASAP 50 POINTS AND BRAINLYEST
Ludmilka [50]

Answer:

Either x = 3, y = 2

or

(3,2) is your answer.

Step-by-step explanation:

2x +y = 8  (1)

y = - x+ 5  (2)

Put equation (2) into equation (1). Use the y value in (2) to go into the y value in (1).

2x - x+5 = 8       Combine the x values

x + 5 =  8            Subtract 5 from both sides

x + 5-5 = 8-5

x=3

Now go back to (2). Put x in for the value of -x. Watch the sign.

y = -3+ 5

y = 2

So the answer is (3,2)
