Answer 1

Answer: 65 degrees

Step-by-step explanation:

Bcoz only the size of angle has changed not the measure

Answer 2

AO =OB(GIVEN)

ANGLE OAB=ANGLE OBA(ANGLES FORMED. AT EQUAL SIDES ARE EQUAL)

SUM=65+65=130 DEGREES

SUM OF ANGLES OF TRIANGLE=180 DEGREES

ANGLE AOB=180-130=50 DEGREES

ANGLE DOC=50 DEGREES(OPPOSITE ANGLES)

ANGLE DOC=ANGLE CDO(THEY ARE FORMED UNDER EQUAL SIDEA(SIMILAR TO FIRST PROOF))

180-50+50=ANGLE ODC

180-100=80 DEGREES
