Question

Find the measurement of ∠A from give figure.​

Answer 1

Answer:

let the angle opposite to angle c (115) be x .

115°+ x = 180° ( linear pair )

x = 180°-115°

x = 65°

According to angle sum property sum of all interior angles of a triangle is 180°

so,

65°+65°+a = 180°

130° + a = 180°

a = 180°-130°

a = 50°
