Answer:
74
Step-by-step explanation:
A polygon's angles add up to (n-2)*180, where n is the total number of sides, and a hexagon has 6 sides, which means its angles add up to 720 degrees.
Therefore, we can set up an equation where the missing angles, marked as x, and the rest of the angles add up to 720:
x+x+152+108+140+172=720
2x+572=720
2x=148
x=74
Therefore, the angles of the 2 missing angles is 74

Answer:
a) 7. (b) 1. (c) 11
Step-by-step explanation:
360/30-1=11
360/45-1=7
360/1801=1
We know that the 2 triangles are proportional and are similar so that means there must be a scale factor between the sides of the triangles. To find the D, we need to use the scale factor and multiply it by CD to find DE. The scale factor can be found by dividing 2 similar sides so: EF divided by DG is 5/1.25 which is 4. We can then multiply the scale factor which is 4 by CD so: 3.25 * 4 is 13. DE = 13
