Is it possible to draw a triangle with these measurements 90° 60° and 60°

lina2011 [118]

Answer:

Step-by-step explanation:

The angles of a triangle must always add up to 180 degrees.

90 + 60 + 60 = 210 degrees.

Therefore it would not be possible to draw a triangle with these values.

Express the equation x = 10 and y = -3 as a linear equation in two variables

34kurt

Answer:

For x = 10:

$x + 0y - 10 = 0$

For y = - 3:

$0x + y + 3 = 0$

Step-by-step Explanation:

Before we start let's recall the formula for the linear equations.

$ax + bx = c$

So first let's solve for x=10:

$x = 10$

Move 10 to the other side.

$x - 10 = 0$

As there is no y given we will simply write 0y.

$x + 0y - 10= 0$

Now let's solve for y=-3:

$y = - 3$

Move -3 to the other side.

$y + 3 = 0$

As there is no x given we will simply write 0x.

$0x + y + 3 = 0$
