Can you draw an isosceles triangle with only one 80 degree angle?

aev [14]

Answer:

The triangle is 50,50 80

Step-by-step explanation:

The three angles of a triangle equal 180 degrees

We only want one 80 degree angle. That means the other two angles have to be the same, since it is an isosceles triangle. Call the other angle x

x+x+80 = 180

2x+80 =180

Subtract 80 from each side

2x+80-80=180-80

2x =100

Divide by 2

2x/2=100/2

x = 50

Each of the other angles in the triangle would have to equal 50 degrees

The triangle is 50,50 80

the graph of a line has a slope of -2/3 and a y intercept of (0,2). rewrite the equation in standard for (Ax+By=C) with a positi

sergiy2304 [10]

Answer:

2x + 3y = 6

Step-by-step explanation:

obtain the equation in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

here m = - $\frac{2}{3}$ and c = 2

y = - $\frac{2}{3}$ x + 2 ← in slope-intercept form

multiply all terms by 3 to eliminate the fraction

3y = - 2x + 6 ( add 2x to both sides )

2x + 3y = 6 ← in standard form

I need help with substitution

Neporo4naja [7]

Answer:

(-7,-15)

Step-by-step explanation:

We can substitute first y in the second y. Both equations are also functions. We can merge the equations.

$2x - 1 = x - 8 \\ 2x - x = - 8 + 1 \\ x = - 7$

Substitute x = -7 in any given equations. I will choose the second equation to substitute in.

$y = x - 8 \\ y = - 7 - 8 \\ y = - 15$

Answer Check

Substitute both x and y in both equations.

$- 15 = 2( - 7) - 1 \\ - 15 = - 14 - 1 \\ - 15 = - 15$

The equation is true for (-7,-15).

$- 15 = - 7 - 8 \\ - 15 = - 15$

The second equation is true for (-7,-15).

Therefore our answer is (-7,-15)
