Answer 1

Answer:

Step-by-step explanation:

(3) THE ANGLE WHICH IS ADJACENT TO THE MARKED 90 DEGREE WILL ALSO BE 90 WHICH IS A PART OF THE GIVEN QUADRILATERAL.

WE KNOW THAT THE TOTAL ANGLE INSIDE A QUADRILATERAL SUMS TO 360 DEGREE

THEREFORE

X+90+110+60= 360

X + 260=360

X = 360-260

X = 100 DEGREE.

(4) TOTAL ANGLE OF 360 IS DIVIDED INTO 9 EQUAL PARTS

THEREFORE EACH ANGLE WILL BE = 360/9

                                                             = 40 DEGREE

HOPE THIS HELPS.

Answer 2

Answer:

The total internal angle of a rectangle is 360°

Now see the attachment

So we get

x+ 90 +110+60=360

Or, x=360-260=100

So x=100°
