Each leg of a 45°-45°-90° triangle measures 12 cm.
vitfil [10]

Answer:

12 sqrt(2)

Step-by-step explanation:

Givens

a = 12 cm

b = 12 cm

c = ??

The triangle is isosceles with 1 right angle and 2 45 degree angles.

Formula

c^2 = a^2 + b^2

c^2 = 12^2 + 12^2

c^2 = 144 + 144

c^2 = 288

c^2 = 144 * 2

c = sqrt(144) * sqrt(2)

c = 12 * sqrt(2)

The answer isn't there. 12*sqrt(2) is the correct answer, 12sqrt(3).

Was this just a typo of some kind.

Answer:

Math is fun dot com. All one word. (With .)

For other straight lines, I’m assuming you are supposed to graph the intersections, just use the two point form to get the rise and run. The rise / run is the slope. Usually called ‘m’ in formula form. Plug each Straight line formula into the Same web page above and it will graph the line for you. Be sure each line is in the [Y = mX+b ]

Format. Y is the up, X is the over, m is the slope. (Change in Y divided by change in X) (like stairs), and ‘b’ is the Y intercept. That means where the line crosses the Y (up) axis.
