answer:
x=-4/7 and the slope is 7
Answer:
Step-by-step explanation:
<u>Area of triangle:</u>
We have the value of b but not h.
Added auxiliary segments which help to find the value of h.
<em>See attached for details</em>
- sin 40° = h/4
- h = 4 sin 40°
- h = 2.57 km
<u>The area is:</u>
- A = 1/2*6*2.57 = 7.71 km²
For these equations, we are going to use the slope formula, as defined below (
is slope and
and
are coordinate points):

We can simply "plug in" the coordinates we are given:


Our answers are:


Number 1 and I think 4 not sure but try those .
