Question

A side of the triangle below has been extended to form an exterior angle of 64°. Find the value of x.

Answer 1

180- 64 =116

x°+18°+116°= 180°

x°+134°=180°

x°=180-134

x°=46°

Answer 2

Answer:

x is 46°

Step-by-step explanation:

subtract 64 from 180 so 180-64.

that gets you 116

add 18 to 116 so 116+18

that is 134

subtract 134 from 180 so 180-134

and then you get 46
