Obtuse. A regular triangle, aka Equilateral, has three 60 degree angles, so if you look at the angles, and visualize it, one angle is 80 degrees, so probably the top one, and the other 2 are smaller angles, giving it the obtuse characterization

−12x−5y=40 12x−11y=88 ​ x= y=
Nezavi [6.7K]
Add the two equations and use the elimination method. The x term will "cancel out" to be able to solve for the y term.

STEP 1
−12x−5y=40
12x−11y=88 ​
x terms "cancels out"; add y terms

-16y= 128
divide both sides by -16

y= -8


STEP 2
substitute y value into either original equation

12x−11y=88 ​

12x - 11(-8)= 88

12x + 88= 88
subtract 88 from both sides

12x= 0
divide both sides by 12; 0 divided by any number is 0

x= 0


ANSWER: x= 0; y= -8

Hope this helps! :)
