Question

Find the missing value

Answer 1

Answer:

10. 20

11. 35

Step-by-step explanation:

10. The triangle has 3 angles inside where one of the angles is 60 degrees. Another angle can be found by subtracting 180 - 80 = 100. This means the angle next to 80 is 100.

All the angles in the triangle add to 180. So 60 + 100 + x = 180. This means x = 20.

11. The angle 93 has a vertical angle across it within the triangle. This means the triangle has one angle in the triangle of 93. Another angle can be found by subtracting 180 - 128 = 52. Since the angles in a triangle add to 180, then 93 + 52 + x = 180. So x = 35.
