Step-by-step explanation:

reduced triangle

use Pythagoras A²+b²=c2

so 12²+9²

Answer:

36 inches

Step-by-step explanation:

Perimeter of the larger triangle: P1

Perimeter of the smaller triangle: P2

It's probably a right angle triangle. Verifying through pythagoras theorem:

20² = 12² + 16²

400 = 144 + 256

P1 = 20+12+16 = 48

P1/P2 = side1/side2

48/P2 = 16/12

48/P2 = 4/3

P2 = 48 × 3/4

P2 = 36

Solve the system of linear equations by graphing. Round the solution to the nearest tenth.
jeyben [28]

Answer:

The approximate solution to the system is (1.2, 4.4)

x = 1.2 and y = 4.4

Step-by-step explanation:

The solution of the system of linear equations equation y = –0.25x + 4.7 and y = 4.9x – 1.64 is shown in the attached graph. The red line represents the equation y = –0.25x + 4.7 and the blue line represents the equation  = 4.9x – 1.64.

The solution of the system of equations is their point of intersection shown on the graph.

The point of intersection is (1.231, 4.392). To the nearest tenth, it is (1.2, 4,4). So x = 1.2 and y = 4.4.

So the approximate solution to the system is (1.2, 4.4)
