Answer:
10???
Step-by-step explanation:
Since you did not provide a diagram, I made one for easier reference. You are asking what kind of triangle is the one shaded in red. Since a rectangle has two sets of congruent sides, their diagonals are also equal. When two diagonals intersect each other, they make 4 congruent sides. Thus, the triangle is an isosceles triangle, since it has two equal sides ST and TR.
I think it’s A and it’s B at the most but still...A
SLOPE: 3 Y INTERCEPT: 3
The other answer is not correct!!!
