Question

find the value of x ​

Answer 1

QUESTION:

• FIND X

ANSWER:

ANGLE D = 90° ( BY FIGURE )

• Consider point y

y =180 - 90 = 90°

• Consider point k

IN TRIANGLE EDC,

ANGLE( E + D + C ) = 180° ( SUM OF ANGLES OF A TRIANGLE)

K + Y + 50 = 180

K + 90 + 50 = 180

K = 180 - 140 = 40°

NOW,

ANGLE K + ANGLE X = 180° ( ANGELS ON A STRAIGHT LINE)

ANGLE X = 180 - 40 = 140°

HENCE ANGLE X IS 140°
