Answer:
rectangle = 180
triangle = 350
the triangle has a much larger area.
350-180=170
the triangle by 17
square inches
Answer:
2y-2n-3a
Step-by-step explanation:
(7y-2n) - (5y+3a)
7y-2n-5y-3a
2y-2n-3a
Based on the lengths of the given triangles and the length of segment BD, the length of segment AD is 22.20.
<h3>What is the length of segment AD?</h3>
The triangle ABC is a right angled triangle with segment AB being the hypothenuse.
We can therefore find this length using the Pythagoras Rule:
Hypothenuse ² = a² + b²
Hypothenuse ² = 28.6² + 23.2²
Hypothenuse ² = 1,356.20
Hypothenuse = √1,356.20
= 36.83
Length of AD:
= AB - BD
= 36.83 - 14.60
= 22.2

Answer:
Step-by-step explanation:
The total surface area of a cone is given by :
Put r = 2r and l = 2l in the above formula
Hence, the total surface area of the cone is 
.
(2x+4)+(4x+2)+(2x-1)=180
8x+5=180°
8x=180-5
8x=175
X=21.875
A= 2(21.875)+4=47.75
B=4(21.875)+2 =89.5
C=2(21.875)-1=42.75
