Answer:
d
Step-by-step explanation:
Find : Which statements are always true regarding the triangle
m∠5 + m∠3 = m∠1
m∠3 + m∠4 + m∠5 = 180°
m∠5 + m∠6 =180°
m∠2 + m∠3 = m∠6
m∠2 + m∠3 + m∠5 = 180°
Solution:
External angle of triangle = Sum of opposite interior angles
m∠1 = m ∠3 + m∠5
m∠4 = m ∠2 + m∠5
m∠6 = m ∠2 + m∠3
12x = 12; x = 1
That simple
-28 because if you add 8 to -120 you get -112 then divide it by 4 and you got -28
For this you simply plug in a 3 wherever you see k so it would be 15(3) which is 45. Hope this helps!
