Answer:
Step-by-step explanation:
A triangle is isosceles if it has two equal sides and two equal angles.
From the diagram, the two perpendicular bisectors divides each base angle into 2 equal parts.
Since the 2 lines of the the perpendicular bisectors cuts across the midpoint of the triangle, it divides both lines JL and LK equally.
This means that lines JL and LK are equal.
Triangle JLK has 3 sides, JL, LK and JK.
Since lines JL and LK are equal, then
Triangle JLK is isosceles since it has two equal sides and 2 equal angles
Answer:
No Solution
Step-by-step explanation:
8x+2y=13 4x+y=11 Subtract 4x on both sides to isolate y
y=-4x+11 <---- Substitute this equation into the
equation 8x+2y=13
8x+2(-4x+11)=13
8x-8x+22=13
22=13 (not true)

3 |a-b| +2|b-1|
a= -2 and b=-4
3 |-2--4| +2|-4-1|
3 |-2+4| +2|-4-1|
3 |2| +2|-5|
Absolute value means takes whatever is inside and make it positive
3*2 +2*5
