Answer:
the value of y=2
here ,
(2x-1,3y-2)=(x+2,2y)
then,
3y-2=2y{corresponding elements}
3y-2y=2
or, y=2
hence the value of y=2
Answer:
90 cm
Step-by-step explanation:
Let the side of the square be S
Area of the square = S² = 64
So, S = √64 = 8 cm
Let L be the length of the rectangle and B be the breadth
We know B = S = 8
Area of rectangle = BL = 8L
Total area = Area of square + area of rectangle
Total area = 64 + 8L = 232 (given)
Subtracting 64 from both sides yields
8L = 232-64 = 168 or L = 168/8 = 21
Perimeter of square = 4S = 4 x 8 = 32
Perimeter of rectangle = 2(B + L) = 2(8 + 21) = 2 x 29 = 58
Total perimeter = 32 + 58 = 90 cm
Question number 9
Angle 1 is 75. This is because If two parallel lines are cut by a transversal, the corresponding angles are congruent.
Angle 2 is 105. This is because If two parallel lines are cut by a transversal, the interior angles on the same side of the transversal are supplementary.
Question number 10
Angle 1 is 120. This is because If two parallel lines are cut by a transversal, the corresponding angles are congruent.
Angle 2 is 60. This is because If two parallel lines are cut by a transversal, the interior angles on the same side of the transversal are supplementary.
Easy, do 12 divided by 5 = 12/5
=
2.4
