Answer:

We must have two angles and a side.

A is the correct option.

Step-by-step explanation:

For any triangle ABC,  the law of sine is given by

\frac{a}{\sin A}=\frac{b}{\sin B}=\frac{c}{\sin C}

From this formula it is clear that in order to find the length of the side of the triangle, we must have two angles and a side.

Let us understand this by assuming that we need to find a (length of the side). From the formula, we have

\frac{a}{\sin A}=\frac{b}{\sin B}\\\\a=\frac{b\sin A}{\sin B}

Thus, to find the length a, we must have b, sin A and sin B.

Hence, o find the length of the side of the triangle, we must have two angles and a side.

Need help dont know how to round <br><br>round this number to the nearest thousand? 0.7966347977​
tatyana61 [14]

Answer:

.797

Step-by-step explanation:

If your talking about a decimal number, you would say the <u>thousandth</u>. I know, weird, but don't blame me.

To round up, any number above 5 rounds up to the next value place, and any number below 5 rounds down to the last value place.

Ex:   1.3483838383

Since 8 is greater than 5, we could get rid of all the 83s and just round up to 1.35.

So the thousandths place in a decimal would be 0.79<u>6</u>66357977, so we just ask if the next number after the thousandths place is greater than 5. The place number after .796 is 6, so since it is greater than 5, we would round up to .797.

Our answer is .797.

Hope this helps!

PLEASE HELP!!!!!! The length of a rectangle is three times its width. If the perimeter of the rectangle is 56 cm, find its area.
Alexus [3.1K]

Step-by-step explanation:

l = length

w = width

l = 3w

perimeter p = 2l + 2w = 56

using the identity of the first equation

p = 2(3w) + 2w = 56

6w + 2w = 56

8w = 56

w = 7 cm

l = 3w = 3×7 = 21 cm

so, the area is

l×w = 21×7 = 147 cm²
