Answer 1

Answer:

mark me as brainliest

Step-by-step explanation:

Q1

a) angle ACD= 180-70 ( linear pair ) ACD= 110

b) angle ABC = 180-(70+50) ( angle sum property of triangle ) ABC = 60

Q2

120 = y+y

120= 2y

60 = y

each angle is 60

Q3

as we know the base angles are equal in iscoscales triangle so let them be y

y+y+100 = 180 ( angle sum property of triangle )

2y= 180-100=80

y=80/2

y= 40

Q4

if B = 40 then also C = 40 (base angles are equal in iscoscales triangle)

40+40+A= 180 (angle sum of triangles)

80+A=180

A=180-80

A=100

Q5

yes they can be sides of triangle because of the property :-

lowest side + lower side should be greater then largest side

8+10 is great er then 12

so yes it can be a triangle

Answer 2

Answer:

It reduces soil erosion and flood hazards by collecting rainwater and reducing the flow of stormwater to prevent urban flooding. Most buildings that utilize rainwater harvesting systems have a built-in catchment area on top of the roof, which has a capacity of collecting large volumes of water in case of rainstorms.
