Answer:

5^2+h^2=12^2, the answer would be ~10.97 ft.

Step-by-step explanation:

I would use the Pythagorean theorem to solve this problem. Put in the things that you know, so in this image we are given one of the legs and the hypotenuse of the triangle.

Pythagorean theorem is :

a^2+b^2=c^2 with a and b being the legs and c being the hypotenuse.

Once you plug in the hypotenuse and one of the legs, solve for the other leg by subtracting a^2 (5^2) from 12^2 (c^2), which will give you 119, and then take the square root of 119 and you will get your answer.

A straight road crosses two parallel railway tracks. The angle between the road and the

Mumz [18]

<h3>Answer: 95 degrees</h3>

=======================================================

Explanation:

I recommend drawing it out to see what's going on. See the drawing below.

In the diagram, both angles are in the northeast corner of their four-corner configurations. They are both congruent corresponding angles. So that's why the second angle is also 95 degrees.

Side note: we could replace "northeast" with any of the other directions on the compass (such as southwest). All that matters is that they are in the same configuration.

The speed of an airplane is 885 km per hour. Find the distance covered by the airplane in 3 hours and 20 minutes. Also, express

torisob [31]

Answer:

$2.95\cdot 10^3\:\mathrm{km}$

Step-by-step explanation:

Distance is given by $D=st$ , where $s$ represents speed or rate and $t$ represents time.

What we're given:

speed of $885\:\mathrm{km/h}$
time of $3.\overline{3}$ hours

Thus, the distance covered by the airplane is:

$d=885\cdot 3.\overline{3}=2,950\:\mathrm{km}$

In scientific notation:

$2,950\:\mathrm{km}\implies\boxed{2.95\cdot 10^3\:\mathrm{km}}$

In what way does knowing the measures of the three sides of a triangle tell you more than just knowing the measures of the three

ankoles [38]

Answer:

Step-by-step explanation:

Knowing the measure of the three angles can help us know if the triangle is acute, obtuse, right, isosceles, or equilateral and also compared with another we can tell if it is similar to another Δ.

Knowing the measures or the three sides of a triangle we can know if the triangle is right, isosceles, or equilateral and also compared with another we can tell if it is congruent or similar with another Δ.

We can see that knowing the sides will tell us more about the congruency of triangles whereas knowing just the angles can tell us that triangles are similar yet we will not know if the triangles are also congruent.
