Because i already found what they were or you just have to explain how i found it and then on 16 you just have to find it and then on 18 you just explain.

11. to find <DAC a triangle will equal to 180° so subtract 100 and 32 from 180° which will give you 48.

12. is 145° not 35° because you add the two angles your given and and subtract from 180° a triangle will ALWAYS equal to 180°

13. To find <BAC a triangle will equal to 180° so subtract 88 and 57 from 180 which will give you 145°

14. is actually the same answers as 11 cause the the angle you need to find will always be the middle number which is the vertex. they both have the same vertex which is <A

15. will be the same as 11 as well.

16. <P will equal to 49.5

17 and 18. <B will actually be 90° if you see that square symbol it actually indicates it's a 90 degree angle. <A will be 48° and to find <C you add all the angles and subtract it by 180 which will give you 42°

hope this helps I'm taking geometry as well keeps practicing and this will get so easy. if you find any mistakes comment ❣

W-14=t. that i think is the answer idk
