Answer:
49°, 59°, 72°
Step-by-step explanation:
Angles of a triangle must add up to 180°.
49° + 59° + 72° = 180°
28° + 58° + 62° = 148°
39° + 89° + 108° = 236°
45° + 70° + 85° = 200°
Only the first set could represent the interior angles of a triangle.
Answer:
i think its conditional. i think its conditional because your'e using outside references to come up with an explanation. i hope this helps. good luck.
Step-by-step explanation:
Answer:
l = 33 feet
Step-by-step explanation:
Let length be l.
Width, b = 2l-1
Perimeter of the room, P = 196
We know that the perimeter of the rectangle is given by :
P = 2(l+b)
196=2(l+2l-1)
98=3l-1
Adding 1 both sides.
98+1=3l-1+1
3l=99
l = 33 feet
So, the length of the room is 33 feet.
