Answer:

There can Only be 1 Right angle in a Triangle!

Step-by-step explanation:

Triangles have 180 degrees in total, If You had Two Right Angles, Then it would equal 180, since there is three angles,three sides and etc on a triangle that won't work. In a Triangle you could have 1 right angle and Two 45 degree angles to get your total of 180 degrees and a complete Triangle!!

Help ! solve the following system of equations -9x+2y=-13 2x-9y=20

Stella [2.4K]

Answer: x = 1, y = -2

Step-by-step explanation:

-9x+2y=-13

x= 13/9 + 2/9y

2x-9y=20

2(13/9+2/9y)-9y=20

Substitute y with -2.

x= 13/9+2/9(-2)

After solving you'll see that 1 is a possible solution for x.

Check your answer

-9x+2y=-13

-9x1+2(-2) = -13

2x-9y=20

2x1-9(-2) = 20

-13 = -13

20 = 20

Therefore, x=1 and y=-2
