Question

solve any 2 please... ​

Answer 1

Answer:

14)

angle inner of Pentagon = 540 deg

and given angles are 40 and 60 deg >>> 100 deg >>> 40  +  60

540 - 100 = 440 deg left

1 : 3 : 7 >>>1 + 3 + 7 = 11

1/11 * 440 = 40 deg angle 1

3/11 * 440 = 120 deg angle 2

7/11 * 440 = 280 deg angle 3

Proof:40 + 120 + 280 + 40 + 60 = 160 + 320 + 60 = 480 + 60 = 540 deg :)

13) hexagon = 540 deg,

given here gets us ///

x + 10 + 2x + 20 + 2x - 20 + 3x - 50 + x + 40 + x + 20 =

10x + 20 = 540

10x = 520

x = 52 degree

Proof:

x + 10 + 2x + 20 + 2x - 20 + 3x - 50 + x + 40 + x + 20 =

62 + 124 + 84 + 106 + 92 + 72 = 540 :D

PLEASE MARK BRAINLIEST, GOTTA DO LOT OF WORK AND TIME TO BOOST MATHS :)
