Question

find the angle measure X in the following figure​

Answer 1

Answer:

same way solve this problem

Step-by-step explanation:

y = 180° - 90° [linear pair angles]

y = 90°

Sum of the measures of the external angles is 360°,

60° + 90° + 70° + x + y = 360°

60° + 90° + 70° + x + 90° = 360°

310° + x = 360°

x = 50°
