Answer:
A
Step-by-step explanation:
Because a^2+b^2=c^2 in a right triangle by Pythagorean's Theorem. So, the only one that works is 3^2+4^2=5^2 because 9+16=25.
11-5=6
18-11-7
26-18=8
........... so on and so forth.
I think you get the point.
Answer:
1) Yes 2)No
Step-by-step explanation:
1) Yes because the two shorter lines combined are longer than the base and so those two lines are able to make a triangle.
2) No because the two lines on top will be equal to base line and so the two shorter lines will not be able to make a third angle because it will be level with the base.
It would be 14 for the perimeter
In triangle the sum of the angles =180,and we have angle=124 so,180-124=56.
X=4
