On your geometry test you have two triangles: δabc and δmno. you are told that ∠a ≅ ∠ m and that ∠b ≅ ∠ n. which statement is also true? a) ∠c ≅ ∠o b) ∠a is a right angle c) δabc ≅ δmno d) δmno is a right triangle.

A) ∠C ≅ ∠O

Step-by-step explanation:

For this you´ll have to remember the laws of the triangles, whic state that the sum of all the interior angles of a triangle equals 180º, if you have that A is equal to M and B is equal to N you can figure out that the remaining angle is equal.

Lest give immaginary measures to the angles:

A and M measure 40

B and N measure 110

Angle A+B= 150, the measure of angle C is= 30

Angle M+N=150, the measure of angle O is= 30.

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer
