Heterogeneous student are found in ​

Heterogeneous grouping is a distribution tactic in the classroom, whereby diverse students (for example, students that have learning disabilities and students who are gifted) are placed in different classrooms so that they can apply their skills and abilities more evenly through their cohort.

hope this helps u!!

if triangle abc is congruent to triangle def, their interior angles are congruent, because congruent parts of congruent triangles are congruent (cpctc).

that means ∠d is congruent to ∠a; ∠d is equal to 8x - 2.

interior angles of all triangles add to equal 180 degrees, so you can set the sum of these interior angle values equal to 180 and solve for x.

180 = (8x - 2) + 22 + 72

180 = 8x - 2 + 22 + 72

180 = 8x + 92

88 = 8x

11 = x

x = 11
