Step-by-step explanation:
Let us take ratio constant as 'x'
Therefore ratio of angles
3x:5x:9x:13x
Sum of interior angles of quadrilateral is 360 degree.
3x+5x+9x+13x=sum of interior angles of quadrilateral
=>3x+5x+9x+13x=360
=>30x=360
=>x=12
Answer:
Angle F
14)9
15)6
16)57
17)29
Answer: Isolate the variable by dividing each side by factors that don't contain the variable.
x= -7, -9
