Answer:
X = 7.2
Step-by-step explanation:
Hello
For the triangle of right side, using Pytagoras:
(2.5)^2 + b^2 = 6^2
6.25 + b^2 = 36
b^2 = 36 - 6.25
b^2 = 29.75
b = 5.45
Now we can to find X using again Pytagoras:
3^2 + (5.45)^2 = x^2
9 + 29.75 = x^2
38.75 = x^2
X = 7.2
Best regards
Answer:
(c) {13,16,30}
Step-by-step explanation:
In order for the sides lengths to form a triangle, the sum of the shortest two must exceed the longest.
That will not be the case for ...
{13, 16, 30}
because 13 +16 = 29 < 30.
(13, 16, 30} could not form a triangle
