Question

What is the measure of the missing angle?
280
1200

Answer 1

32°

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°
