3. find all solutions of the linear congruence 3x - 7y = 11 (mod 13). 4. solve each of the following sets of simultaneous congruences: (a) xel (mod 3), x = 2 (mod 5), x = 3 (mod 7). (b) x = 5 (mod 11), x = 14 (mod 29), x = 15 (mod 31). (c) = 5 (mod 6), x = 4(mod 11), r = 3 (mod 17). (d) 2x = 1 (mod 5), 3x = 9 (mod 6). 4x = 1 (mod 7), 5.x = 9 (mod 11). - 1 connee 73 med 2 3 5 b abestem

sorry, i'm new here and i'm just trying to figure this out. try quizlet. rate 5* you!

9) i can't see the angle so whatever it is just do this: cos(angle) x hypotenuse and then use that answer and they hypotenuse and plug it into this: (answer you just got)^2 + b^2 = (hypotenuse)^2. the first answer will be the answer of the adjacent side and the second answer after this equation will be the opposite side.

10) y = 14 x = √147 or 12.12435565

11) x = 4.8

12) x = 4.2

13) x = 9.3

14) pq: 13.2

qr : 17.6

angle p: 53º

15) angle c: 54.3º

angle a: 35.7º

16) h = 21040

v = 1841

step-by-step explanation:

10) 7/sin(30) = 14 = y

7^2 + b^2 = 14^2

49 + b^2 = 196

b^2 = 196 - 49

√b^2 = √147

x = √147

11) cos(70) x 14 = 4.788282007

x = 4.8

12) tan(25) x 9 = 4.196768923

x = 4.2

13) sin(31) x 18 = 9.270685348

x = 9.3

14) pq: sin(37) x 22 = 13.23993051

pq: 13.2

qr: cos(37) x 22 = 17.56998122

qr : 17.6

angle p: 180 - (37 + 90) = 53º

15) cos-1(7/12) = 54.31466529

angle c: 54.3º

angle a: 180 - (90 + 54.31466529) = 35.68533471

angle a: 35.7º

16) 4 x 5280 = 21120

cos(5) x 21120

h = 21039.63202

h = 21040

sin(5) x 21120

v = 1840.729287

v = 1841

i think it is 18

step-by-step explanation:

the answer is 8/21

hope this
