Question

find measure of largest angle
​one of the angle of a quadrilateral is right angle that other three angles are (x - 10) (30+2x) and (5x+30)​

Answer 1

Answer:

The answer is in the pic

Answer 2

Angle 1=90
Angle 2=x-10
Angle 3 =30-2x
Angle 4=5x+30

As per the question,
90+x-10+30-2x+5x+30=360(angle sum property)
4x+140=360
4x=360-140=220
x=220/4=55

Angle2=x-10=55-10=45
Angle3=30-2x=30-2(55)=-80
Angle 4=5x+30=5(55)+30=305


Angle 1=90
Angle 2=45
Angle 3 =-80
Angle 4=305
Sum=360
