Answer:

AB = 5

Step-by-step explanation:

The side opposite the 30 degree angle will have the shortest length. The side opposite the 60 degree angle will be √3 times as long, and the side opposite the 90 degree angle will be twice as long.

In this case we just divide 10 by 2

−5y+3x=3<br> −8y+9x=−12<br> <br> What is X and Y please.

Tomtit [17]

Answer:

( -4, -3 )

Step-by-step explanation:

Let's solve by elimination. Reason being there are no variables without coefficients.

−5y+3x=3 Multiply equation by 3. Each term.

−8y+9x=−12

-15y + 9x = 9 Subtract the to equations

-8y + 9x = -12

___________

-7y = 21

y = -3

Substitute y into original equation

-5(-3) + 3x = 3

15 + 3x = 3 Subtract 15 both sides

3x = -12 Divide by 3, both sides

x = -4
