(11 x2) (12 x 2)
22 : 24
or
(11x3) (12 x 3)
33 : 36
both are equivalent to 11/12
sorry I don't know Ab = cd and bc = ad
Using SAS postulate triangles formed by ABC = abd
Opposite sides are equal and each angle is 90 degrees so by definition it is a rectangle.Ab = cd and bc = ad

Since the ratio of of second variable to the ratio of first variable remains constant i.e y/x =8 so, the linear relationship is direct variation.
Step-by-step explanation:
A relationship is said to have direct variation if ratio of second variable to the ratio of first variable remains constant.
A relationship is direct variation if
where k is the constant.
Now checking if the given data is having direct variation or not.
x y
3 24
4 32
5 40
6 48
Now finding y/x
if y=24 and x = 3 then y/x = 24/3 = 8
if y=32 and x = 4 then y/x =32/4=8
if y=40 and x = 5 then y/x =40/5 =8
if y=48 and x = 6 then y/x =48/6= 8
Since the ratio of of second variable to the ratio of first variable remains constant i.e y/x =8 so, the linear relationship is direct variation.

Answer:
77
Step-by-step explanation:
We can use two different methods to find our missing angle:
Subtract the two known angles from 180° :
Plug the two angles into the formula and use algebra: a + b + c = 180°
