2. an isoceles triangle has two angles that are the same (on the base) so fine the one you don’t know. There are 180 degrees in a triangle 50 + 50 = 100 the remaining angle is…

i think thats what number 2 is asking

So in this case, plug in A= 5 and B=2

to get

5^2 + 2^2 = C^2

25 + 4 = C^2

C = square root of 29

2. In all triangles, the three angles add up to 180 degrees.

In an Isoceles triangle, the two base angles are congruent, or equal in measure.

So if the Base Angle = 50, the other is also 50.

180 – 100 leaves 80 degrees for the Vertex Angle (between the two equal Base Angles).

a squared + b squared = c squared, where c is the hypotenuse.
