I’m going to say pre-algebra because that’s when I learned it in my school system but you may also learn it in algebra as well, College ready math can start in 8th grade math but I would think it would be in highschool.
The sum of the measures of the angles of a triangle is 180 degrees.
An isosceles triangle has two congruent sides.
The angles opposite the congruent sides are congruent.
Just like the bottom left angle measures x, the bottom right angle also measures x.
x + x + 38 = 180
2x + 38 = 180
2x = 142
x = 71

3442
Step-by-step explanation:
Step-by-step explanation:
I do not see your diagram. Triangles can be isosceles, scalene, equilateral, degenerate, etc.
Isosceles; 2 congruent sides and angles
Scalene: no congruent sides and angles
Equilateral: 3 congruent sides and angles
Degenerate: The sum of two sides is equal to the length of the other one, looks like a line segment.
