PLease help me it says use cosine law

zubka84 [21]

Answer:

59 degrees

Step-by-step explanation:

law of cosines states that

for sides A B C and angle c opposite to side C,

$C = \sqrt{A^2 + B^2-2ABcos(c)} \\cos(c) = \frac{c^2-a^2-b^2}{-2ab}$

cos(b) = $\frac{13^2-6^2-15^2}{-2(6)(15)} = 23/45$

cos-1(23/45) = b

b = 59
