Answer:
See below.
Step-by-step explanation:
Using the right triangle altitude theorem, the correct proportions are:





AC = 20 cm





CB = 15 cm
If you are saying 72 / 8 then its 9 it's only reversed multiplication
Answer:
Height of tree= 20
Please give me brainliest if you can
Step-by-step explanation:
x= height of tree
2/3= x/30
3x= 2(30)
3x= 60
/3 /3
x= 20
Answer:
the answer is A.
Step-by-step explanation:
Answer:
The slop of line perpendicular to line y =
x - 2 is ( - 3)
Step-by-step explanation:
Given Line equation as ,
y =
x - 2
The equation of line is y = mx + c
Slop of this line (m1) = 
Now second line with slop (m2) is perpendicular to line first , then
(m1) × (m2) = - 1
So, (m2) =
Or , (m2) = 
∴ (m2) = - 3
Hence the slop of line perpendicular to line y =
x - 2 is ( - 3) Answer
