Question

if two adjacent angles of a parallelogram are {5x-5] and [10x+35] then the ratio of these angles is ?

Answer 1

Answer:

ratio = 1:5

Step-by-step explanation:

because:

In a parallelogram,

adjacent angles makes a sum of 180,

5x -5 + 10x+35 = 180

15x + 30 = 180

15x  = 150

x = 10

now,

put the value of x to find angles

5 * 10 - 5 = 45

10*10 + 35 = 135

and hence

ratio = 45/135 = 1/5 = 1:5
