Answer:
The answer to your question is: letter D
Step-by-step explanation:
First we need to find the distances between the points,
distance AB = 8 get it just by counting the points in the graph
distance AC = 9 get it just by counting the points in the graph
To know the distance BC, use the pythagorean theorem
c2 = a2 +b2
c2 = 8² + 9²
c² = 64 + 81
c² = 145
c = 12.04
Finally, perimeter = AB + AC + BC
= 8 + 9 + 12.04
= 29.04 units
Since two sides are congruent, the opposite angles are congruent.
Angles A and B have the same measure.
m<A = m<B = 34
m<A + m<B m<C = 180
34 + 34 + m<C = 180
68 + m<C = 180
m<C = 112
m<C = 4y = 112
4y = 112
y = 28
