Answer:
32°
Step-by-step explanation:
to understand the solving steps
you need to know about:
- triangle contains 180°
- acute triangles
- PEMDAS
- equation
given
angles:28°,120°
to find:
missing angle
let's solve:
let missing angle be x
as we know
a triangle contains 180° (always)
so,
according to the question
x+28°+120°=180°
x+148°=180°
x=180°-148°
x=32°
