To solve, remember that \(\Delta ABC\) is an equiangular triangle, so all three angles are equal. They mainly involve finding out the value of specified unknown angles of a triangle. The measures of two angles are offered as algebraic expressions in Part A and three angles in Part B. 17 7. Practice: The triangle Inequality Theorem states that the sum of the lengths of any two sides of a triangle is greater than the length of the third side. To nd the value of x, use #GFJ. A factor is a number that can divide another number completely without a remainder. This way, kids can easily learn and make corrections if they get a question wrong. /Resources 15 0 R C!6_Ps@P|_~Bnw"= Learning .
