an isosceles triangle is a triangle with two twin sides, and therefore two twin angles.
if one angle is 98°, well, we can't have another 98° angle because that makes 98+98 = 196°, and the sum of all interior angles in a triangle cannot be more than 180°.
so the other remaining angles must be the twin smaller angles, namely 180 - 98 = 82, and each twin takes half of that, namely 41°.

Answer:
C 2
Step-by-step explanation:
-3 doubled = -6
-6 +8 = 2 so C 2

Answer:
Triangle ITA is the answer.
Step-by-step explanation:
<S = <I means that the triangle IRS is an isoscles.
The midpoint (T) cutting both congruent side length sides at the same angle means that Line TG and Line TA are equal.
Also T being the midpoint means Line TI = Line TS.
Given that angles <G and <A are same.
You can use SSA (side-side-angle) to prove triangles are congruent so line SG is equal to Line IA.
It should be 7.615773106
But rounded should be 7.6
