Answer:

any positive angle such that B+C=135

Step-by-step explanation:

Hope this may help you

for triangle

A+B+C=180

Given A=45

45+B+C=180

B+C=180-45

B+C=135

but no negative and zero angles of B and C

Answer 2

Answer:

let angle B =x

C=x

triangle,

A+B+C=180

45+x+x=180. (a=45,b=x,c=x)

45+2x=180

2x=180-45

2x=135

x=135/2

x=67.5

B= 67.5,C=67.5
