Question

Find out the value of m and the three angles if the angle in a triangle are m-49,m-20,m+60

Answer 1

Answer:

m = 63

Step-by-step explanation:

We know that sum of all interior angles of any triangle is 180°.

therefore,

$(m - 49) + (m - 20) + (m + 60) = 180°$

=> $3m - 9 = 180$

=> $3m = 180 + 9$

=> $3m = 189$

=> $m = \frac{189}{3}$

=> $m = 63$

hence, m = 63
