1. if triangle DEF is congruent to triangle MNO, then side DF is congruent ro side ? 2. If triangle DEF is congruent to triangle MNO, then triangle FDE is congruent to triangle?

A)OMN
B)MNO
C)NOM
D)ONM

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180

im not sure but my dad knows

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
