Question

Find x on the following figure
( Isosceles triangle class 9)

Answer 1

Answer:

x=50°

Step-by-step explanation:

Angle C +angle ACD =180°

Therefore angle ACD = 50°

Since it is an isoceles triangle x will be equal to ACD i.e. 50°

Answer 2

Answer:

x= 50°

angle ACD + 130 = 180 {linear pair}

angleACD= 50°

since ΔABC is an isosceles Δ

therefore angle x= angle ACD
