Answer:
The value of ∠BDC is equal to 68°.
Step-by-step explanation:
It is given that,
∠BDA is a straight angle.
ATQ,
∠BDC+∠ADC=180 (Linear pair)
-7x+12+(-8x)+48 = 180
-7x+12-8x+48 = 180
-15x+ 60 = 180
-15x = 180-60
-15x = 120
x = -8
So,
∠BDC = -7x+12
= -7(-8) + 12
= 56+12
= 68°
So, the value of ∠BDC is equal to 68°.
Answer:
x = 17/7
Step-by-step explanation:
Given-
<em>
= 
</em>
<em> = 
</em>
<em> = 
</em>
<em> = 
</em>
<em>On comparing both sides- </em>
<em> x - 8 = - 6 x + 9</em>
<em>7 x = 17</em>
<em>x = 17/7</em>
∴ x = 17/7.
Answer:
B (2, 4)
Step-by-step explanation:
A (-1,-9); M (0.5, -2.5); B (xB, yB)
M is the midpoint of AB, therefore we have these 2 equations:
(*) xA + xB = 2. xM
(**) yA + yB = 2. yM
(*) <=> xB = 2. xM - xA = 2x0.5 - (-1) = 1 + 1 = 2
(**) <=> yB = 2. yM - yA = 2x(-2.5) - (-9) = -5 + 9 = 4
So, B (2, 4)
