I’m stressed and tired only do circled ones

10. 48 degrees 11. Use explanation below. 12. 25 degrees 13.Use explanation below. 14. 63 degrees 15. Use explanation below. 16. 130.5 17. A. 48 degrees B. 90 degrees and C. 42 degrees 18. Explain

Step-by-step explanation:

10. All triangles angles add up to 180 degrees, so 100+32=132 and 180-132=48

11. Use the explanation above.

12. Using the rule above 88+57=145 and 180-145= 25

13. Use explanation above.

14. Add the two answers from 10 and 12. 48+25= 63

15. Use explanation above.

16. Using the triangle 180 degrees rule add 90 degrees (Angle a is a right angle which is always 90 degrees) to 40.5 degrees. 40.5 + 90= 130.5

17. You have angle A (48) angle B is a right angle aka 90 degrees and using the rule 90+ 48= 138 and 180-138= 42

18. I think you can explain it now (I hope)

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
