Question

Find the magnitude of the angle ​

Answer 1

Answer:

Step-by-step explanation:

Let angle adjacent to angle 120 degrees be x, and angle adjacent to angle 130 degrees be y and unknown angle at the top of the triangle be z

120 + x = 180

x = 180-120

x = 60

130 + y = 180

y = 180 - 130

y = 50

x + y + z = 180

60 + 50 + z = 180

110 + z = 180

z = 180 -110

z = 70
