Answer:
15 children can divide them with eachother, each get 2 sweaters and 3 trousers
Step-by-step explanation:
15×2=30
15×3=45
75+(2x-5)=180 (they form a straight angle)
Combine like terms
2x+70=180
Subtract 70 from both sides
2x=110
Divide both sides by 2
x=55
Angle y is the vertical angle of angle (2x-5). Therefore, they are equivalent in terms of degrees.
y= 2x-5
y=2(55)-5
y=110-5
y=105
Final answer: x=55, y=105

Step-by-step explanation:
Answer:
Total area to cover the bridge = 17.52 m²≅
Step-by-step explanation:
The triangular panels are equilateral triangles
Area of equilateral triangles = A= (√3/4)a² where a= 1.7 meters
Since there are 14 panes Area = 14 x (√3/4)a² = 14 x (√3/4)1.7² = 17.52 m²≅
