Question

The four angles of a quadrilateral are in the ratio 1 : 2 : 3 : 4. The measure of its smallest angle is *

Answer 1

1+2+3+4=10

Smallest angle-1/10×360=36°

Answer 2

Answer:

This is the right answer

Step-by-step explanation:

Let the angles of a quadrilateral be 1q 2q 3q and 4q

we know the sum of quadrilateral is 360 °

1q+2q+3q+4q=360°

10q=360°

q=360/10

=36

1q=1×36=36

2q=2×36=72

3q=3×36=108

4q=4×36=144

So the measurement of smallest angle is 36 °
