Answer:
Definition of bisector
Angle addition postulate
same side interior angles theorem
subtraction property of equality
Step-by-step explanation:
It is given that m║n, m∠1 = 65°,m∠2=60° and BD --> bisects ∠ABC . Because of triangle sum theorem, m∠3 = 55°. By the definition of bisector , ∠3 ≅∠4, so m∠4= 55°. Using the angle addition postulate , m∠ABC = 110°, m∠5 = 110° because vertical angles are congruent . Because of same side interior angles theorem, m∠5 +m∠6 = 180°. Substituting gives 110°+ m∠6 =180°, so by the subtraction property of equality , m∠6 = 70°.
It would be: k+3 = 10
subtracting 3 from both sides,
k+3-3 = 10-3
k=7
Answer:
50
Step-by-step explanation:
I just think it's 50 because I was on this problem for a long time and I just took my best guess
Check the picture below.
so notice, their perimeter is the same, because the perimeter is just one rod anyway, and all rods are the same length, thus
