Question

Two triangles can be formed with the given information. Use the Law of Sines to solve the triangles.
B = 29°, b = 26, c = 28

Answer 1

two answers are possible .because the congruency is not sure a,s,sproperty will not give unique answer. but any way you use sine formula to solve

Answer 2

A = 92.5°, C = 58.5°, a = 53.6; A = 87.5°, C = 121.5°, a = 53.6

A = 92.5°, C = 58.5°, a = 12.6; A = 87.5°, C = 121.5°, a = 12.6

A = 119.5°, C = 31.5°, a = 46.7; A = 2.5°, C = 148.5°, a = 2.3

A = 119.5°, C = 31.5°, a = 14.5; A = 2.5°, C = 148.5°, a = 14.5

Answer 3

sinA/a=sinB/b=sinC/c

Answer 4

im not clear on how to do that though:/

Answer 5

sinB/b=sinC/c solve for C

Answer 6

use cosine formula to solve for a.namely a^2=b^2+c^2-2bc cosA

Answer 7

here A will have two values according to A+B+C=180. Amay be accute or obtuse

Answer 8

ok so how would i plug in those numbers to the cos formula? im not good at this at all

Answer 9

i just dont know where the A comes from

Answer 10

first B may have two values as sin function is positive in 1st and 2nd quadrent. for both the values you solve for A.If B+C is more than 180 Bcan not be obtuse. sssthere is only one solution.

Answer 11

triangle prperty .Sum of aaaaangles in a triangle is 180 deg

Answer 12

ok so how can i find the answer? im still lost

Answer 13

first step use sinB/b=sinC/c

Answer 14

find sinC

Answer 15

i did and i got a weird decimal. how do i find sinC

Answer 16

sinB/b=.018

Answer 17

namely sinC=(c/b)sinB

Answer 18

WHAT IS YOUR SINc

Answer 19

sinC=.522?

Answer 20

REFER THE TRIGNOMETRY TABLE AND FIND THE ANGLE FOR WHICH .522 IS OCCURING

Answer 21

i dont see it on there
