Answer:
(a) 3 ft, 4 ft, 5 ft
Step-by-step explanation:
The triangle inequality requires the sum of the two short sides exceed the long side.
__
a) 3 ft + 4 ft = 7 ft > 5 ft . . . . . triangle is possible
b) 4 yd + 1 2/3 yd = 5 2/3 yd < 10 yd . . . . not a possible triangle
c) 3 ft + 3 ft = 6 ft < 7 ft . . . . not a possible triangle
d) 4 in + 4 in = 8 in . . . . not a possible triangle (not greater than 8 in)
__
The first set of side lengths can form a triangle: 3 ft, 4 ft, 5 ft.
Answer:
y=5x−83y=x+18 (the question is wrong; it has 2 equal signs)
y+5(3)=15
y+15=15 (multiply 5*3; you get 15)
y= 15-15
y= 0
-20 because after the the thermometer hits zero the more negative the temperature gets the colder it is
By definition, supplementary angles are those whose sum is 180°
Therefore, ∠2 = 180 - ∠1
2x + 4 = 180 - 124
2x = 52
x = 26°
8 and 24 let me know if this helps
