Area of triangle with points (7,7) (10,3) (7,3)

Mathematics
1 answer:
aksik [14]3 years ago
3 0

Answer:

Area = 6

Step-by-step explanation:

Given

(x_1,y_1) = (7,7)

(x_2,y_2) = (10,3)

(x_3,y_3) = (7,3)

Required

The area

This is calculated as:

Area = \frac{1}{2}|x_1y_2 - x_2y_1 + x_2y_3 - x_3y_2 +x_3y_1 - x_1y_3|

So, we have:

Area = \frac{1}{2}|7*3 - 10*7 + 10*3 - 7*3 +7*7 - 7*3|

Using a calculator, we have:

Area = \frac{1}{2}|-12|

Remove bracket

Area = \frac{1}{2}*12

Area = 6

Using proportions.
18. x
--- =. ----
270. 30,330

Cross multiply
18 x 30,330 = 545,940

IM STUMPED I USUALLY LOVE THESE PROBLEMS :( The least common multiple of x, 10 and 14 is 70. What is the greatest possible value
Keith_Richards [23]

Answer:

x=70

Step-by-step explanation:

If we know that the LCM of 10, 14 and x will be 70, that means x has to be a factor of 70.

First, let's find the multiples of 10 and 14 until they equal 70.

10: 10,20,30,40,50,60,70

14:14,28,42,56,70

Since we're asking for the greatest value of x, that means that x has to be smaller or equal to than 70 but still large enough to be the greatest.

Hey, isn't 70 a factor of 70? The remainder gets to 1 which is a whole number, so 70 is a multiple of 70.

So, x = 70.

Hope this helped!
