AB=18km

Step-by-step explanation:

In any triangle in 2 dimensions our interior angles should equal to 180°.

We know 2 of the three interior angles, since we know it must sum up to 180° let's subtract these known interior angles to obtain:

180°-79°-68°=33°

Furthermore, since this triangle is not a right triangle we cannot use the Pythagorean equation.  Therefore let's use the law of sines:

Where A is angle A=33°, B = 68°, C=79°, a = CB, b=AC, c=AB.

Since we want to find side AB and we know A, a, and C we only use 2 of those parts of the law of sines and so:

d is the correct answer

step-by-step explanation:

x= 8 because 3x = 3 * 8, and 3*8 = 24

27/4x^6 y^8

step-by-step explanation:

4(3x^2y^4)^3 (2x^3y^5)^4

=

108x^6 y^12 /16x^12 y^20

=

108 /16x^6 y^8

=

27 /4x^6 y^8
