Question

1. The angles of a quadrilateral are in the ratio 1:2:3 : 4. Find the smallest angle
​

Answer 1

Answer:

36°

Step-by-step explanation:

Let the angles be 1x, 2x, 3x and 4x

Sum of angles of quadrilateral = 360°

1x + 2x + 3x + 4x = 360°

10x= 360°

x = 36°

Therefore, smallest angle=36°

Answer 2

Answer:

X+2x+3x+4x=360°

Step-by-step explanation:

10x=360° x=360°/10 x=36° therefore the angles are=36° 2x=2×36=72° 3x=3×36=108°, 4x=4×36=144°. the smallest angle are =2 angle
