Question

A quadrilateral has two angles that measures 240 and 35. The other two angles are in a ratio or 6:11. What are the measures of those two angles?

Answer 1

240+35+6x+11x=360

17x=85

x=5

Other two angles are 6×5,11×5

=30,55

Answer 2

Step-by-step explanation:

lets take 6:11 as 6x and 11x

now we know that the sum of all 4 angles of a quadrilateral is always 360 so -

240 + 35+ 6x + 11x = 360

275 + 17x = 360

17x = 360 - 275

17x = 85

x = 85 / 17

x = 5

now the angles which were =

6x = 6 * 5= 30 degree

11x = 11 * 5 = 55 degree
