Question

the measure of threee angles of a triangle is 50,60 &x find the value of x
​

Answer 1

Answer:

$50 + 60 + x = 180 \\ (angle \: sum \: property) \\ = 110 + x = 180 \\ = x = 180 - 110 \\ = x = 70$

this may help you please follow me and give thanks..

Answer 2

The sum of three angles of Triangle is 180

50 + 60 + x = 180

110 + x = 180

× = 180 - 110

= 70

The value of x is 70
