Please Find the value of x and y

Free_Kalibri [48]

Answer: x=40° and y=140°

Step-by-step explanation:

From the figure, we know that x and 40 are vertical angles. Therefore, they are equal to each other.

x=40°

With the value of x, we know that x and y are supplementary angles. That means they are equal to 180°.

40+y=180 [subtract both sides by 40]

y=140°

Now we know x=40° and y=140°.

If B=16°45’ and c=13 then find a (picture provided)

SIZIF [17.4K]

Answer:

A. 12.4

Step-by-step explanation:

To find a, we'll use the Law of Sines that says:

$\frac{a}{sin(A)} = \frac{c}{sin(C)}$

And we'll isolate a to get:

$a = \frac{sin(A) * c}{sin(C)}$

We first need to find A, which is easy. The sum of the interior angles of a triangle is 180 degrees... and we already have 2 of them, so:

A = 180 - 90 - 16.75 = 73.25

(converted 16°45' to 16.75)

Then we will plug-in the information we already have

$c = \frac{sin(73.25) * 13}{sin(90)} = 12.45$

So, let's round it to 12.4 to match the answer A.
