Answer:
I'm guessing that makes obtuse triangle
why don't you try draw the triangle
Acute triangle : 0<x<90 degrees
right triangle : x=90 degrees
obtuse triangle :triangles that angles are bigger than 90 but smaller than 180 degrees
reflex angle:bigger than 180 but smaller than 360 degrees
Answer:
I think its a. (-2,-4)
Step-by-step explanation:
<span>2x+3y=3
</span><span>-3x-2y=8
3y=3-2x
-2y = 8+3x
y = 1 - 2x/3
y = -4 - 3x/2
</span>1 - 2x/3 = -4 - 3x/2
5 = - 3x/2 + 2x/3
5 = -9x/6 + 4x/6
5 = -5x/6
x = 5 * 6/-5
x = -6
No plug it in.
<span>2x+3y=3 ; x = -6
-12 + 3y = 3
3y=3+12
3y=15
y = 5
So </span>x = -6 and y = 5
1. angles 2 and 5 are supplementary, reason : it's given
2. 3 and 2 are congruent reason: they are vertical
3. 3 and 5 are supplementary reason : substitution prop. (i think so)
4. I don't know this one but are their any options?
The area of a square is one of the sides squared s^2
