Question

in triangle abc angle a =55 ° angle c=75°. find the measure of angle b. please ​

Answer 1

Step-by-step explanation:

sum of all angle of traingle is 180

<a +<b +<c = 180

55+75+<c =180

130+<c =180

<c = 180-130

<c= 50

Answer 2

Answer:

given angle a=55° and angle c=75° then angle b=?

by using angle sum property angle a+b+c=180°

55°+b+75°=180

130°+b=180

b= 50°
