Determine whether aabc should be solved by using the law of sines or the law of cosines. then solve the triangle.

a = 35º, b = 13, a = 11

a.) law of sines: b = 42.7, c = 102.3º. 318.

b.) law of sines; b = 102.3°, c = 42.7°, c = 18.7

c.) law of cosines; b = 106.2°, c = 38.8°, c = 18.7

d.) law of cosines; b = 38.8°, c = 106.2°, c = 18.7

B = 42.7 degrees, C = 102.3 degrees and c = 18.7.

Step-by-step explanation:

We use the Sine Rule:

a / sin A = b / sin B

11 / sin 35 = 13 / sin B

11 sin B =  13 sin 35

sin B = 13 sin 35 / 11 = 0.677863

B = 42.7 degrees.

So C =  180 - 42.7 - 35

= 102.3 degrees.

c / sin 102.3 = 11 / sin 35

c =  11 sin 102.3 / sin 35

= 18.7.

if i remember correctly with perpendicular stuff you just take away the negative
