Question

please answer correct and in detail.​

Answer 1

Answer:

Let the unknown angle be x

55 + 75 + X = 180 (sum of angles of triangle)

X= 180-55-75

X = 50

Step-by-step explanation:

75 + 50 + X = 180 ( sum of angles of triangle)

X = 180 - 75 - 50

X = 55

X+y=180 (sum of angles in straight line)

55 +y =180

Y = 180 - 55

Y =75
