Answer:
Step-by-step explanation:
As angle 6y° and angle( 13y - 10 )° are interior angles on the same side of transversal their sum will be equal to 180° .
Then :-
Which means :-
= 13y - 10
= 13 × 10 - 10
= 130 - 10
= 120°
Then angle 6y :-
= 6 × 10
= 60°
As angle 60° and angle 9x + 12° are a linear their sum will also add up to form 180° .
Which can be written as :-
Then :-
= Angle 9x + 12
= 9 × 12 + 12
= 108 + 12
= 120°
Therefore , the value of y = 10 and the value of x = 12 .
Answer:
x =5
Step-by-step explanation:
6 + 8 ( x - 1) = 2 (3x + 4)
Distribute
6+8x-8 = 6x+8
Combine like terms
8x -2 = 6x +8
Subtract 6x from each side
8x-6x -2 = 6x -6x+8
2x -2 =8
Add 2 to each side
2x-2 +2 = 8+2
2x = 10
2x/2 = 10/2
x =5
Answer:
wouldnt X be 0.6?
