Question

The four angles of a quadrilateral
are (x - 10)°, (x + 20)°, (2x + 50)°
and 2.xº. Find the four angles.​

Answer 1

Answer:

all angles are 80,80,100,100

Step-by-step explanation:

2x -20+x+30+x+50+2x=360

6x+60=360

x+10=60

x=50

all angles are 2(50-10),(50+30),(50+50),(2*50)

all angles are 80,80,100,100

Answer 2

Answer:

(x-10)+(x+20)+(x+50)+2x=360  [ Because sum of interiro angles of any                        quadrilateral is 360]

or, x-10+x+20+x+50+2x=360

or, 5x +60 =360

or, 5x = 300

or, x = 300/5

or, x = 60

Therefore angles of the quadrilaterals are:

x-10 = 60 -10=50

x+20 = 60 +20 =80

x+50 =60 +50 =110

2x = 2 * 60 =120

This is the answer my friend...
