Question

Find the value of the angle 'b’ in the given figure.​

Answer 1

Step-by-step explanation:

let the triangle be ABC

ang.A = 90°

ang.B = x

ang.C = 36°

sum of all ang. in a triangle = 180°

x = ang.A + ang.C + x = 180°

90 + 36 + x = 180

126 + x = 180

x = 180 - 126

x = 54° ans

Answer 2

Answer:

(i) 126 (ii) 54

Step-by-step explanation:

(i) 36+90=b(exterior angle property)

126=b

(ii) 76=32+b

76-32=b

54=b
