Question

the two acute angles of an obtuse angled triangle,whose obtuse angle measure 131digre, are
in the ratio 2.5.Find the angles​

Answer 1

Answer:

one is 14,and another is 3

w.k.t sum of all angles of a triangle is 180

now consider triangle as ABC and

angle A is obtuse angle,

A+B+C=180•

131+B+C=180•

B+C=180-131=49

B+C=49 ALSO B+C=7x now

x=7and B=17AND C=35
