Question

ABC is a right angled triangle in which ZA=90°andAB=AC.Find_Band_c.​

Answer 1

Answer:

angle b and angle c = 45 degree...therefore the whole triangle becomes and 45-45-90 triangle

Answer 2

Answer:

c is 45°

Step-by-step explanation:

let angle C = x

angle A = 90°

In ∆ ABC

A+B+C = 180°

90°+x+x=180°

90°+2x=180°

2x= 180-90°

2x=90°

x=90°÷2

x=45°

now,

A+B+C=180°

90°+45°+x=180°

135°+x=180°

x=180°-135°

x=45°

c=45°
