Answer:
Step-by-step explanation:
The top triangle is similar to the whole triangle because of AAA
Then we know that the corresponding sides are similar
9/81=(3x-20)/(3x-20+56)
1/9=(3x-20)/(3x+36)
cross multiply
9(3x-20)=3x+36
27x-180=3x+36
24x=216
x=9
1 + 1 + 1 + 2 = 5
5 x 9 = 45
Therefore, the total number of km is 45.
Answer:
14
Step-by-step explanation:
Answer:
B ( -1,-7)
A (-3,-2)
C (6, -1)
Step-by-step explanation:
<u>Explanation</u>:-
Given vertices are A( -3,2) , B(-1,7) and C(6,1)
Reflection about the x-axis then the coordinate points are transformed to
(x,y)→ (x,-y)
A(-3,2)→ A¹(-3,-2)
B(-1,7)→ B¹(-1,-7)
C(6,1)→ C¹(6,-1)
