How many solutions are possible for a triangle with B=44, a=23 and b=12?

1 answer:

5 0

B = 44 degrees
a = 23
b = 12
use law of sines to solve for angle A:
b/sinB = a/sinA
12/sin44 = 23/sinA
12sinA = 23*sin44
sinA = (23*sin44)/12
sinA = 1.3314
since sinx is only defined for values between -1 and 1 it is impossible to form a triangle with given the dimensions. hence no possible solutions

Solve: (x ÷ 4) + 8 = 38

First you have to rewrite the equation:
(x ÷ 4) + 8 = 38

Second you have to write the division as fraction:
(¼x) + 8 = 38

Third you have to take off the unecessary bracket:

¼x + 8 = 38

Fourth multiply 8 and 38 by 4
x + 32 = 152

Fifth step move the constant to the right hand and change the sign.
x = 152 - 32

Then subtract:

x = 120

Hope this helps :))

1, when you factor you get 6x(x^2-1)+4(x^2-1)= $(6x+4)(x-1)(x+1)$
