<span>f(x) = 2x + 1

y = 2x + 1

x = 2y + 1

x - 1 = 2y

0.5x - 0.5 =

f^-1(x)</span>

A triangle, ABC, has coordinates A (-2, 0), B (-2, 5) and C (-4, 0). What is the length of the shortest side?
Usimov [2.4K]

Answer: 2 units.

Step-by-step explanation: When you graph the points given, it gives you this shape in the image below.  The hypotenuse (longest side of triangle) is found by doing the following:

a^2 + b^2 = c^2, where a and b are the legs (the other sides of the triangle) and c is the hypotenuse.

5^2 + 2^2 = 29.

√ 29 ≈ 5.38, and that is the length of the hypotenuse.

The shortest side is the bottom side, which is 2 units.  Therefore, that is your answer.

Let me know if this is right! :)

Please help me with this​
Diano4ka-milaya [45]

Let the third angle of the triangle be y.

y + 64° + 45° = 180° (angle sum of triangle is 180°)

x + y = 180° (angle of a straight line is 180°)

Notice that they both equal 180°. This means that they are the same thing, hence:

y + 64° + 45° = x + y

Since y = y, it is not necessary to write them down. Remove y from both sides of the equation:

64° + 45° = x

Surprise! exterior angle = sum of interior opposite angles.

I hope this clears up any confusion you might have. If not, feel free to leave a comment with your question.
