Answer:
Step-by-step explanation:
take 55 degree as reference angle
using tan rule
tan 55=opposite/adjacent
1.42=37/x
x=37/1.42
x=26.05
Answer:
let the angles be 7x , 13x , 16x
7x + 13x + 16x = 180 ( sum of angles in a triangle is 180 degree)
36x = 180
x = 180 / 36
x = 5
therefore the angles are:
7 X 5 = 35 degree
13 X 5 = 65 degree
16 x 5 = 80 degree
