Answer:
Area of the triangle covered by the cars = 910.45 square km
Step-by-step explanation:
Since, all the sides of triangle ABC are given,
And formula for the area of a triangle with all sides given is,
Area =
Here, s =
And a, b, c are the measures of the sides of the triangle.
If a = 39 km, b = 87 km and c = 58 km
s =
s = 92
Therefore, (s - a) = 92 - 39
= 53
(s - b) = 92 - 87
= 5
(s - c) = 92 - 58
= 34
Now area of the triangle ABC =
=
= 910.45 km²
Area of the triangle covered by the cars = 910.45 square km
Answer: x = 15
Step-by-step explanation:
First, we will have to acknowledge that Angle M is a complementary angle (that means that it is 90 degrees) meaning that 2x° + 4x° will equal 90 degrees. So, let’s set up this equation.
90 = 2x + 4x
90 = 6x
=
15 = x
Therefore, the x is 15.
x +1 x^2 +5x +4 x +1 (x +1)(x +4)
---------------- / ---------------------- = ----------------- / ----------------------- =
x^2 +x -6 x +4 (x +3)(x -2) x +4
x +1 1 1
= ---------------- * ----------- = ------------------
(x +3)(x -2) ( x +1) (x +3)(x -2)
so the second choice is right sure
5(15)+(15)(15)=75+225
