6 0

Answer:

Step-by-step explanation:

2x-6y=2 ....(1)

-4x+8y=-8....(2)

divid the equation (2) by : - 2 x +4y = - 4...(3)

add (1) and (3 ) :2x-6y - 2 x +4y =2-4

-2y=-2

y = 1

put y=1 in (1) : 2x-6(1)=2

2x=8

Find the area of the right triangle. If necessary, round to the nearest tenth
Ad libitum [116K]

Answer:

B. 150 yards

Step-by-step explanation:

Area of a Triangle = .5 * Base * height

So we need the height of the triangle, or the missing side.

We have to use Pythagorean Theorem to solve this:

A^2 + B^2 = C^2

15 ^ 2 + B ^ 2 = 25 ^2

b^2 = 25^2 - 15 ^ 2

b^2 = 625 - 225

b^2 = 400

sqrt (400) = 20

The missing height is 20. Now we plug it into 1/2 * b * H

.5 * 15 * 20

7.5 * 20 = 150

150 Yds
