Step-by-step explanation:
3(x+2) + 35 + 52 = 180 ( Angle sum property)
3x+ 6 + 87 = 180
3x + 93 = 180
3x = 180 - 93 = 87
x= 87/ 3
x = 29
∠C = 3 ( 29 + 2)
= 3 x 31
= 93
The answer is 80. This is because we can find the area of one of the triangles by (4*8)/2 = 16. We multiply this by 4 since there are 4 triangles. 16*4 = 64. Now finally, we add the area of the base to this value. 4*4+64=80. Therefore the answer is 80 cm^2
X+2.5 because you dont know her height of last year which would give you the variable X and this year she grew 2.5 inches which would make the equation X+2.5

Answer: 60 gallons
Step-by-step explanation:
5 minute = 30 gallons
10 minutes will use double as m uch water because it's double as much time
Therefore, it will use 60 gallons of water
