In △ABC, m∠A=39 △ A B C , m ∠ A = 39 °, a=11 a = 11 , and b=13 b = 13 . Find c c to the nearest tenth.

Answers

Answer:

$c=17.5\ units$

Step-by-step explanation:

step 1

Find the measure of angle B

Applying the law of sines

$(a)/(sin(A))=(b)/(sin(B))$

substitute the given values

$(11)/(sin(39\°))=(13)/(sin(B))$

$sin(B)={sin(39\°)}(13)/(11)$

$B=arcsin[sin(39\°)(13)/(11)]$

$B=48.1\°$

step 2

Find the measure of angle C

Remember that the sum of the interior angles of a triangle must be equal to 180 degrees

$A+B+C=180\°$

substitute the given values

$39\°+48.1\°+C=180\°$

$87.1\°+C=180\°$

$C=180\°-87.1\°=92.9\°$

step 3

Find the length side of c

Applying the law of sines

$(a)/(sin(A))=(c)/(sin(C))$

substitute the given values

$(11)/(sin(39\°))=(c)/(sin(92.9\°))$

$c=(11)/(sin(39\°))sin(92.9\°)$

$c=17.5\ units$

What is 2.16 repeat rewrite as a fraction

Answers

2.16 repeat as a fraction is:

x = 2.16666666
10x = 21.6666666
100x = 216.666666
100x - 10x = 216.666666 (repeat) - 21.6666666 (repeat) = 195
90x = 195
x = 195 / 90
x = (195/3) / (90/3)
x = 65 / 30
x = (65/5) / (30/5)
x = 13 / 6

x = 13/6

HELP PLEASE!!!!!! I need help on 5. My answer was wrong. THIS IS DUE TOMORROW. 25 points for this.

Answers

Answer:

Step-by-step explanation:

Because side BD is similar to side BA

triangle BCD seems to be double the size of triangle BAD

By finding the side lengths of the missing sides BC and CD you can get the perimeter.

Because we know the triangle is double the size you can double the lengths of AD and BD to get 24 and 18, if you add 6,9,24, and 18. You will get 57.

A restaurant claims to have served 352,000,000 hamburgers. What is this number in scientific notation?

Answers

Answer:

3.52 × 10⁸

Step-by-step explanation:

Scientific notation is written in: Number that is in the ones place × 10^power.

Here, the number is 3.52, since 3 has the largest placement.

The power on the 10 should be the number of 0's on 352,000,000/3.52. That is 100,000,000. That number has 8 0's, so the power is to the 8th.

Putting that together, this number in scientific notation in 3.52 × 10⁸.
