Answer 1

Answer:

<b=<c since it's an isosceles triangle

<b=1.5<a=<c

<a+<b+<c=180

<a+1.5<a+1.5<a=180

4<a=180

<a=45

<b=67.5

<c=67.5

Answer 2

Answer:

Step-by-step explanation:

as AB =BC

angle A=C=x(let it be)

angle B =3/2A

angle b=3/2of x

now 3x/2 +x+x =180(angle(A+B+C=180) angle sum property)

7x/2=180

7x=360

x=51 =A=C(approx.)

B=76.5
