Question

Angles of a quadrilateral are in the ratio of 2:3:5:8.Find the smallest angle. *​

Answer 1

Answer:

let the first angle be 2x

then second angle be 3x

then third angle be 5x

then fourth angle be 8x

》2x+3x+5x+8x=360

》18x=360

》x=360/18

》x=20

first angle =2x=2×20=40

second angle =3x=3×20=60

third angle = 5x=5×20=100

fourth angle =8x=8×20=160

smallest angle = 40

Answer 2

Answer:

The ratio of sides = 2:3:5:8

smallest angle = ?

Step-by-step explanation:

total sum = 2+3+5+8 = 18

smallest angle = 2/18 × 360 = 40°

other angle = 3/18 × 360 = 60°

other angle = 5/18 × 360 = 100°

other angle = 8/18 × 360 = 160°

smallest angle = 40°
