(a) 120°
(b) 140°
(c) 60°
(d) 80°

Respuesta :

Answer:

(d)

Step-by-step explanation:

sum the parts of the ratio, 2 + 3 + 4 = 9 parts

Divide 180° by 9 to find the value of one part of the ratio

180° ÷ 9 = 20° ← value of 1 part of ratio , then

4 parts = 4 × 20° = 80° ← largest angle
I think The solve is 80 (d)
