Answer:
Step-by-step explanation:
Given that,
The base of a triangle = 2 km
The perpendicular height of the triangle =
We need to find the value of x. It is the Hypotenuse of the triangle. It can be solved as :
So, the value of x is equal to .
1. A,B and I believe the second would be E
Let x+y=10 be equation (1)
and y=x-4 be equation (2)
from (2)
y=x-4...(3)
sub (3) into (1)
x+(x-4)=10
x+x-4=10
2x=12
x=6
sub (x) into (3)
y=6-4
y=2
