Question

a+b+c=11 cm,major B=60 degree ,major C=75 degree , construct a traingle​

Answer 1

we know that the sum of interior angles = 180°

a+b+c =180°

wkt a=11 ,b= 60, c=?

11+60+x=180

71+x=180

x=180-71

x = 109° = c

Answer 2

Answer:

A+b+c=180

Step-by-step explanation:

A=11cm b=60 c=? 11+60+x=180 71+x=180 x=180-71=

X=109
