MCDA+mBCD=180
mBCD=180-66=114 degrees
Option C
Answer:
Option (3)
Step-by-step explanation:
Given: EF = 10x + 20
FG = 43
EG = 183
From the figure attached,
Length of segment EF + length of segment FG = length of segment EG
By substituting the values of each segment in the equation,
(10x + 20) + 43 = 183
10x + 20 = 183 - 43
10x = 140 - 20
x =
x = 12
Therefore, x = 12 will be the answer.
Option (3) will be the correct option.
<span>Line LM= x+5 and is proportional to line QR which equals 30. Line LN= 50 and is proportional to line QS which equals 75.
</span>The answer is 11.3
Answer:
A 5
Step-by-step explanation:
Parts on the left have the same ratio as parts on the right.
... x/(x+5) = (x -2)/(x +1)
Multiplying by (x+5)(x+1), we get
... x(x +1) = (x -2)(x +5)
... x² +x = x² +3x -10 . . . . eliminate parentheses
... 0 = 2x -10 . . . . . . . . . . subtract x²+x
... 0 = x -5 . . . . . . . . . . . . divide by 2
... 5 = x . . . . . . . . . . . . . . . add 5
