Question

In triangle ABCD. The angles ABCD are in the ratio 1:2:3:4. Write the measure of the greatest angle of quadrilateral.

Answer 1

Answer:72 degrees

Step-by-step explanation:

sum of all the angles of the triangle = 180

ratio is 1:2:3:4

therefore it is divided into 1+2+3+4=10 parts

degree of one part = 180/10

                                = 18

Degree of greatest angle is ratio 4 so the greatest angle = 4 times 18

                                                                                               = 72 degrees
