Question

Two angles of a triangle is 40 degree and 55 degree. Find the measure of third angle. Also

state it’s type.​

Answer 1

Answer:

third angle is 85 degree

Answer 2

let the given triangle be ABC
abgle A= 40 degree,B=55 degree
To find angle C
Using ASP of triangle ABC
40 degree+55 degree +angle C=180 degree
95 degree + angle C=180
Angle C=180-95
Angle C = 85 degree .....ans

As all angles are less than 90 degree, therefore it us an acute angled triangle
