Question

Please help I am failing math

Answer 1

45+85+x=180(sum of angle of triangle)

or, 130+x=180

or, x=180-130

x=50

Explanation:

here, the sum of angle of triangle is 180

Answer 2

x = 50°

Explanation:

According to Angle sum property of triangle,

x + 45° + 85° = 180°

=> x = 180 - 85 - 45

=> x = 180 - 130

=> x = 50

Hence,

The missing angle x is 50° (Ans)
