Question

in the given fig. angleA=60° and angleB=70, then find angle ACD ​

Answer 1

Step-by-step explanation:

We know,

Sum of three angles of a triangle,

A + B + C = 180°

=>60° + 70° + C = 180°

=>C = 180° - 130° = 50°

Now,

C + ACD = 180°

=>50° + ACD = 180°

=> ACD = 180° - 50°

=>ACD = 130° ✓✓✓
