Have a good day! Brainliest?
Answer:
(E) 9
Step-by-step explanation:
I found what numbers worked in all three cases. I found that when a = 4 b = 5 c = 0, all of the equations were satisfied.
Equation 1 4 + 5 = 9
Equation 2 4 + 0 = 4
Equation 3 5 + 0 = 5
Also, a + b+ c or 4 + 5 + 0 = 9
If these answers are correct, please make me Brainliest!
Bisector => AD = CD => 3y+6 = 5y-18 => 2y = 24
=> y=12
Answer:
Answer is B
Step-by-step explanation:
Given that there are two shapes.
On the left there is a triangle WXY and it is transformed into a shape on the right as W'X'Y'.
Since original is WXY we write as WXY is transformed into W'X'Y'
WX will become W'X' and XY as X'y' and so on.
Hence correct answer is option B
WXY --> W'X'Y'
Answer:
Let the two equal angles be x,
so,
x + x + 138° = 180°
or, 2x = 180° - 138°
or, 2x = 42°
so, x = 42°/2
so, x = 21°
21° is the answer.
