Answer:

0.8\sqrt{7} or 2.12

Step-by-step explanation:

<em><u>To solve this, you have to split 28 into two of its factors. We can choose 7 and 4 (can be multiplied together to get 28):</u></em>

                                                       28

                                                   7         4

<em><u>However, 4 can also be split/factored:</u></em>

                                                       28

                                                   7         4

                                                          2       2

<u><em>So now we have a a pair of identical terms (being 2), so take this outside of the radical, like so (leave the 7 there):</em></u>

(2)(0.4)\sqrt{7}

0.8\sqrt{7} or 2.12

Find 2004-04-02-04-00_files/i0340000.jpg. Round the answer to the nearest tenth.
lesya692 [45]

<span>The problem is to calculate the angles of the triangle. However, it is not clear which angle you have to calculate, so we are going to calculate all of them
</span>
we know that
Applying the law of cosines
c²=a²+b²-2*a*b*cos C------> cos C=[a²+b²-c²]/[2*a*b]
a=12.5
b=15
c=11
so
 cos C=[a²+b²-c²]/[2*a*b]--->  cos C=[12.5²+15²-11²]/[2*12.5*15]
cos C=0.694------------> C=arc cos (0.694)-----> C=46.05°-----> C=46.1°

applying the law of sines calculate angle B
15 sin B=11/sin 46.1-----> 15*sin 46.1=11*sin B----> sin B=15*sin 46.1/11
 sin B=15*sin 46.1/11-----> sin B=0.9826----> B=arc sin (0.9826)
B=79.3°

calculate angle A
A+B+C=180------> A=180-B-C-----> A=180-79.3-46.1----> A=54.6°

the angles of the triangle are
A=54.6°
B=79.3°
C=46.1°
