1 answer:

Acute < 90
Right = 90
Obtuse > 90
This triangle is 104 degree so it is obtuse.

Isosceles = 2 same size
Scalene = no same size
Equilateral = all same size
You can see their is mark on 2 sides so it would be isosceles

For which value of a are the graphs of –4 = 3x + 6y and ax – 8y = 12 parallel? a = –4 a = a = a = 2

anygoal [31]

-4 = 3x + 6y
6y = -3x - 4
y = -1/2x - 2/3.....slope here is -1/2. A parallel line will have the same slope

ax - 8y = 12
-8y = -ax + 12
y = (-a/-8)x + 12......so a would have to be -4 because -(-4) / -8 = -4/8 = -1/2

ur answer is : a = -4
