Use the law of sines to solve the triangle.
6.) a=60 degrees, a=9, c=10

sinA /a = sin C / c

sin 60/9 = sin C / 10

(√3/2)/9 = sinC/ 10

√3/18 = sin C / 10

so c will be sin inverse ((10√3)/10)

Step-by-step explanation:

step-by-step explanation:

|ab| = 1.4 = 4

h = 1.4 = 4

a(abc) area = 4.4 = 16/2 = 8

area of abc = 8 cm^2

good luck ! ; )

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1
