Question

21. The following figure is a rectangle in which
x:y=3:7; find the values of x and y.
​

Answer 1

Answer:

x = 27 degrees

y = 63 degrees

Step-by-step explanation:

x+y+90 = 180 (angle sum property in triangle)

we now ratio of x and y is 3a:7a ( a is a variable)

3a+7a+90 = 180

10a = 180 - 90

a = 90 / 10

a = 9

x = 3a = 3*9 = 27

y = 7a = 7*9 = 63
