Answer:
0.5
Step-by-step explanation:
Add up equation 1 and 2 to eliminate b
(a+b)+(-b+c)=3+3 => a+c=6
subtract this new equation from the third equation:
(a+2c)-(a+c)=10-3 =>c=4
plug in c=4 in a+c=6 =>a=2
a+b=3, a=2 =>b=1
well, you already know an absolute value expression has a ± siblings, so let's proceed without much fuss.
Answer: 15 pongs you say?
Step-by-step explanation:
Mapping the triangle on one another simply means you use rigid transformations, which involve scaling. So the second triangle is congruent.
Since 3 is the shortest side, 27 pairs with three, so:
27/3 = 9
The second triangle is 9 times larger.
Using this we can do:
5 * 9 = 45
6 * 9 = 54
since 6 is the largest side, 54 is our answer! Or is it?
Note that this is a right triangle, so we use the Pythagorean theorem to find the hypotenuse.
=
so 9*sqrt(34) is our answer
