The answer is 56 since you do 34 plus 90 and subtract that from 180
Subtract 7 from 4 and Mark it on the grid, then, in order to reflect it, mark the same line in the (-,+) corner. (new coordinates are (-5,7)(-5,3)
Answer:
B
Step-by-step explanation:
reflexive postulate of equality
Step-by-step explanation:
Given :-
The length of the garden 8m greater than 2 times the width.
Area of the garden is 280 m²
Let us consider the length as x and width as y.
Sp, we can day length as :-
x = 8 + 2y ---(1)
Now, we know that:-
Area of Rectangle = Length × Breadth
280 = x * y
We can replace the value of x now,
280 = y × ( 8 + 2y)
280 = 8y + 2y²
2y² + 8y - 280 = 0
y² + 4y - 140 = 0
Factorise it.
(y -10)(y + 14)
Cancelling -ve value, we get the width as 10 metres.
