Question

The brackets for a shelf are in the shape of a triangle ABC. Find the missing angle of the triangle if the measure of the angles a=33 and b=102

Answer 1

`\small\bold\green{[Sum \: of \: interior \: angles \: of \: a \: triangle \: is \: 180°]}`

Lets , Find the missing angle :

↪ m∠A + m∠B + m∠C = 180°

↪ 33° +102° + m² = 180°

↪ 135° + m∠C = 180°

↪ m∠C = 180° - 135°

↪ m∠C = 45°

Answer 2

• 45°

Explanation:

Sum of interior angles of a triangle is 180°.

Find the missing angle:

• m∠A + m∠B + m∠C = 180°
• 33° + 102° + m∠C = 180
• 135° + m∠C = 180°
• m∠C = 180° - 135°
• m∠C = 45°
