Question

in the figure, AB = AC. Find angle ACB, angle BAC, angle MCA and angle PAB​

Answer 1

Answer:

acb=70

acm=110

bac=40

pab=140

Step-by-step explanation:

ab≅ac

abc≅acb(isosceles triangle theorem)

acb=70

mca+acb=180(linear pair)

mca+70=180

mca=180-70

mca=110

bac+abc+acb=180(sum of measures of angle of triangle=180)

bac+70+70=180

bac+140=180

bac=180-140

bac=40

pab+bac=180(linear pair)

pab+40=180

pab=180-40

pab=140
