Answer:

Step-by-step explanation:

You are given two sides and the included angle, so you need to use the law of cosines.

c² = a² + b² - 2ab cos C

c² = 12² + 13² - 2(12)(13)cos 134°

c² = 313 - 312(-0.6947)

c² = 529.733

c = 23.016

Now use the law of sines.

c/sin C = a/sin A

23.016/sin 134° = 12/sin A

sin A = 12 × sin 134° / 23.016

sin A = 0.37504

A = 22.03°

B = 180° - 134° - 22.03°

B = 23.97°

m<A = 22°; m<B = 24°; c = 23 km

Answer: B

How do you solve 216 - 202?? -explained-

Serhud [2]

Answer: 216 - 202 = 14

Step-by-step explanation:

It’s 14 because in my way, I separated the numbers, like this:

200 - 200 = 0

16 - 2 = 14

Since 0 is equal to nothing, the answer is 14.

Find the area of the parallelogram 300 in^230 in^260 in^250 in^2

andrew11 [14]

Given

The parallelogram,

To find the area of the parallelogram.

Explanation:

It is given that,

The base of the parallelogram is 10 inches.

And, the height of the parallelogram is 5 inches.

Therefore,

$\begin{gathered} Area\text{ }of\text{ }the\text{ }parallelogram=b\times h \\ =10\times5 \\ =50in^2 \end{gathered}$

Hence, the area of the given parallelogram is 50 in^2.

Answer:

Step-by-step explanation:

From the figure attached,

If the figures shown are congruent (Equal in shape and size), length of all the sides must be equal.

Therefore, sides sides CD and GH must be equal in measures.

Distance between the two points $(x_1,y_1)$ and $(x_2,y_2)$ is given by,

d = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Length of the side CD having ends C(-4, 4) and D(0, 5) will be,

CD = $\sqrt{(-4-0)^2+(4-5)^2}$

CD = $\sqrt{(16+1)}$

= $\sqrt{17}$

Length of GH having ends G(0, -4) and H(4, -5) will be,

GH = $\sqrt{(0-4)^2+(-4+5)^2}$

= $\sqrt{16+1}$

= $\sqrt{17}$

Therefore, m(CD) = m(GH)

Similarly, we can prove all corresponding sides of two figures equal in measure.

This shows ABCD ≅ EFGH.
