Question

how do you do it? Please help :)

Answer 1

Step-by-step explanation:

we will do a small construction

we produced AO till point k

proof

In triangle AOC

AO =OC. WE HAVE GIVEN

ANGLE OAC=ACO

ACO,=25

IN TRANGLE AOC

A+O+C=180

AOC=180-50

AOC=130

AOB=130. AO=OC=OB

AOB=130 SAY EQ 1

BOK=360-(AOC+COK+AOB)

BOK=360-(130+50+130)

,BOK=360-310

BOK=50

COK=OAC+ACO. EXTERIOR ANGLE

COK=25+25

COK=50

BOC=BOK+KOC

X=50+50

X=100
