X=3
Explanation-
(x-1)+(x-2)=3
x-1+(x-2)=3
x-1+x-2=3
Then collect the two like terms
x-1+x-2=3=
2x-1-2=3
Calculate the difference
x-1+x-2=3=
2x-3=3
———————
2x-3=3
Move the constant to the right-hand side and change its sign
2x=3+3
———————————————————-
2x=3+3
Add the numbers
2x=6
————————————————-
2x=6
Divide both sides of the equation by two
X=3
There you go. Have a great day! :)
Answer:
Area of rectangles: l*b [LENGHT×BREADTH]
Therefore,
3/4 × 2/3 = Area
We do it as, 3*2/4*3
⇒ 6/12 = area
After simplification, we will get
1/2 = area of rectangular picture
The supplement angle of angle ABC is 108 degrees because, supplement angles mean angles that add up each other to 180 degrees so 180-72=108
