Answer:
Step-by-step explanation:
Since (8x-20) and (3x+2) are two sides of the angles on one plane, we can structure them into an equation to find x.
(8x-20) + (3x+2) = 180
We want x to be on one side and all the numbers to be on the other. But first, we must combine our two problems.
-20 + 2 = -18; 8x + 3x = 11x
So now our equation is:
(11x-18) = 180
In order to move our numbers to one side and leave our x's on the other, we must inverse our additions/subtractions/etc.
180 + 18 = 199
11x = 199
199/11 = 18.1
x=18.1!

B. It’s an initial payment of part of the whole price.
Yes that is one way. You can also prove that a shape is a square by looking at the angles and each side are congruent to each other
Answer:
Step-by-step explanation:
Rectangular prisms have F=6 faces and E=12 edges.
By cutting one corner, we are adding 3 edges.
By cutting two corners, we are adding 2*3 = 6 edges.
Therefore the new solid has 12 + 6 = 18 edges.
Answer:
Step-by-step explanation:
According to Angles of intersecting chords theorem:
∠GAJ = 
Where ∠GAJ = 50 , BD = 24 and GJ = ?
50 = 
Multiplying both sides by 2
100 = 24 + GJ
GJ = 100-24
GJ = 76 degrees
