Answer 1

Answer:

75°

Step-by-step explanation:

AB=AC

so angle B=angle C.............(a theorem)

angleB+C =2x

angles A+B+C= 180°............(sum of all angles of a triangle)

30+2x=180

2x= 150°

so x= y= 75°

Answer 2

Answer:

angle b is 75 and c is also 75

Step-by-step explanation:

since sum of all angles of a triangle is equal to 180degrees

therefore a+b+c=180

and also since the angles opposite to equal sides of a triangle are equal b=c

therefore a+b+c=180

30+x+y=180

since x=y take both as x

therefore 30+x+x=180

30+2x=180

2x=180-30=150

x=75 and y=75

hope its clear and helpful
