Answer 1

558 ° this is measure of other two angle

all of you know 2 angle are added are also 180 equal

Answer 2

Let the other two angles be 8x and 15x

{by angle sum property of a quadrilateral=360०}

solution= 80०+50०+8x+15x=360०

130०+23x=360०

23x =360०-130०

=230०

23x=230०

x=230÷23

x=10

putting the value of x =10

8x = 8×10=80

15x=15×10=150

so other two angles which is in ratio 8:15 is

8o० and 150०
