Question

find angle ACB
angle ADB
angle OAB
​

Answer 1

Answer:

ANGLE ACB = 54°

". OAB = 36°

ANGLE ADB = NOT SURE

Step-by-step explanation:

ANGLE OAB

X+X+108°=180°

2X+108°=180°

2X=180-108°

X = 72/2 = 36

ANGLE ACB

ANGLE CAB = 36°

SO ANGLE ABC = 36+54°=90 (right angle )

SO ACB = X+36+90=180°

X+126=180°

X= 180-126= 54°
