Given: ΔABC; a= 10; b = 13, and ∠C = 70°. Find the length of side c to the nearest whole number

Alexxandr [17]

Answer:

$c=13\ units$

Step-by-step explanation:

we know that

Applying the law of cosines

$c^2=a^2+b^2-2(a)(b)cos(C)$

we have

$a=10\ units\\b=13\ units\\C=70\°$

substitute

$c^2=10^2+13^2-2(10)(13)cos(70\°)$

$c^2=180.07$

$c=13\ units$
