Someone please help me!

The answer to your question is below

Step-by-step explanation:

43.-

x =

x =

x = 29.42

44.-

x =

x =

x = 13.49

45.-

cos x =

cos x = 0.7166

     x = 44.22°

46.-

x =

x =

x = 17.34

47.-

cos P =

cos P = 0.888

     P = 27.36°

sinR/13 = sinP/6

sin R = 13sin27.36/6

sinR = 0.996

   R = 84.71°

Q = 180 - 84.71 - 27.36

Q = 67.93°

48.-

D = 180 - 25 - 113

D = 42°

CD = 9Sin113/sin42

CD = 12.38

ED = 9sin25/sin42

ED = 5.68

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490

step-by-step explanation:

the first 5 right here the next 5 i will upload as separate question
