Question

If two interior opposite angles to exterior angle whose measure is 140⁰ of a triangle are 60⁰ and x respectively then find x​

Answer 1

Answer:

the total angle of triangle = 180

the two interior opposite angles 140

60+60 +60 = 180

Step-by-step explanation:

the outside angle is 140 so 180 - 40 = 140

so the total angle of triangle is 40+60+80= 180

the side of angle is 60 hence proof
