Answer:
12,14,25 I think or A
Step-by-step explanation:
To enable a set of three numbers to represent three sides of a triangle, sum of smaller two numbers must be greater than the largest number. Hence, only C can represent a triangle
Answer:
Length oh two equal sides: 1 16/45 cm
Third side: 2 31/45 cm
Step-by-step explanation:
length of two equal sides is x
Perimeter = x + x + ( x + 1 1/3) = 3x + 1 1/3 = 5 2/5
3x = 5 2/5 - 1 1/3 = 27/5 - 4/3 = 61/15
x = 61/45 = 1 16/45
Third side = 61/45 + 4/3 = 121/45 = 2 31/45
Number of jugs required to hold 18 gallons of water = 18/0.5
= 36
So 36 jugs are required by Jan to empty 18 gallons of water.
All 3 angles of a triangle must equal to 180. You can simply set up an equation to solve this and set it equal to 180.
Angle 1 - 50 + x
Angle 2 - x
Angle 3 - 2x -10
50+x+x+2x-10=180
4x+40=180
4x=140
x=35
Angle 1 = 50+35= 85
Angle 2 = 35
Angle 3 = 2(35) - 10 = 60
60+35+85=180
-8 because when you add a negative number your basically subtracting its absolute value.
