Answer:
The average salary of master's degree people is $ 63,000 And
The average salary of bachelor's degree people is $ 52,000
Step-by-step explanation:
Given in question as :
Let the average salary of master's degree people = $ M And
Let the average salary of bachelor's degree people = $ B
According to question ,
The average salary of master's degree people + The average salary of bachelor's degree people = $115,000
Or , $ M + $ B = $ 115,000 ............. A
Again ,
$ M = 2 × $ B - $ 41,000 ............... B
From eq A and eq B
(2 × $ B - $ 41,000 ) + ( $ B ) = $ 115,000
Or, 3×$ B = 156,000
∴ B = = $ 52,000
And M = $ 115,000 - $ 52,000
∴ M = $ 63,000
Hence The average salary of master's degree people is $ 63,000 And
The average salary of bachelor's degree people is $ 52,000 Answer
Answer:
Step-by-step explanation:
We have given a parallelogram ABCD.
For a parallelogram,
Opposite pair of sides are parallel to each other.
i.e AD is parallel to BC and AB is parallel to CD.
From the attached figure,
∡1 = ∡4 and ∡2 = ∡3 {If two parallel lines cut by a transversal line then alternate interior angles are congruent }
Next, AC ≅ AC {Reflexive identity}
hence, ΔABC ≅ ΔCDA , By Angle-Side-Angle(ASA) congruent property of triangle.
Therefore, AB = CD and AD = BC {Proved}
