Question

in a quadrilateral, if it's four angles are in the ratio 5:2:4:7 then the sum if measures of the first two smaller angles is__________

Urgent!!!!​

Answer 1

Answer:

40 and 80

Step-by-step explanation:

at first we can represent the angles as 5x,2x,4x,and 7x.

as we can see that 2x and 4x are the smallest angles among the following. [ when x is a similar value ]

then

• 5x + 2x + 4x + 7x = 360° [ the sum of all angles of quadrilateral is 360°]
• 18x                        = 360°
• x                           = 360°÷18
• x                           = 20°
• then 2x is equal to 2 ×20° = 40°

• and 4x is equal to 4×20° = 80°

Hope you mark this ans. as BRAINLIEST !

Answer 2

5x + 2x + 4x + 7x = 360

18x = 360

x = 20°

the angles are

5x is 100°

2x is 40°

4x is 80°

7x is 140°

the smaller Angle are 40,80
