ahrayia [7]

Answer:

Step-by-step explanation:

Sum of the angles of a triangle is ALWAYS 180°.

2x+3x+5x = 180°

10x = 180°

x = 18°

2x = 36°

3x = 54°

5x = 90°

The angles are 36°, 54°, and 90°

Which of the following is a correct equation for the line passing through the

kipiarov [429]

Answer:

$2x-3y=-12$

Step-by-step explanation:

We can use the point-slope formula given by:

$y-y_1=m(x-x_1)$

The given line passes through the

point (-3,2) and having slope $m=\frac{2}{3}$ .

We substitute the given point and slope to get:

$y-2=\frac{2}{3}(x--3)$

$y-2=\frac{2}{3}(x+3)$

we clear the fraction to get;

$3y-6=2(x+3)$

$3y-6=2x+6$

$3y-2x=6+6$

$3y-2x=12$

Or in standard form:

$2x-3y=-12$

X+y=8 and 3x+2y=14 for soliving system

kumpel [21]

X+y=8
multiply the first equation by 3 to get rid of x
3x+3y=24
3x+2y=14
subtract equation 1 from 2
y=10
substitute to find the value of x
x+10=8
x=-2
