I need help with 2 questions plzzzzz
1 answer:
Answer:
Step-by-step explanation:
<em>1).</em> x + 6y = 12 ⇔ y = x + 2
3(x - 2) = - y - 4 ⇔ y = - 3x + 2
There is not significant relation between slopes such as:
- "the same" for parallel or the same lines;
- "opposite reciprocals" for perpendicular lines;
Thus, there is only answer option left: "The lines intersect at an angle other than 90°."
<em>2).</em> A(- 2, 3), B(- 2, - 7), C(4, - 5)
AC = = 10
AB = 10
BC = = 2√10
Triangle is Isosceles.

So hmmm check the picture below
in an isosceles triangle, two sides are equal, and thus the angles those twin legs make, are also twin angles
let's say the angle made is "a", so all internal angles will be 64 + a + a = 180
or 64 + 2a = 180
thus 2a = 180 - 64 => 2a = 116, thus a = 116/2
