6 0

Answer:

0

Step-by-step explanation:

Using the sine rule:

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

We substitute the values to get:

\frac{11}{\sin 57}=\frac{19}{\sin B}

We simplify to get:

\sin B=\frac{19 \sin 57}{11}

\sin B=1.45

But we know that the range of the sine function is [-1,1].

This means that, it is not possible to form a triangle with the given measures;

Which expression shows how 6 • 45 can be rewritten using the distributive property?
tatuchka [14]
6*45=270 is the first step you should do to get the answer you are looking for. The next thing I would do is go to all the answers to see which one comes out the same way. The first one comes to be 246, the next one is 54, the next is 270 and the last one is 220. 6*40+6*5 is the correct answer.

Use the distributive property to write an expression equivalent to 9(47).
Ganezh [65]

Seperate the 47 into 2 different numbers at can be added together

40 +7 = 47

So now you have: 9(40+7)


This would become (9 * 40) + (9*7)

The scale of map is 14 cm long. Calculate the actual length of the river in kilometres
Helen [10]

Answer:

Step-by-step explanation:

Given:

1cm = 85 km (on the map)

so map is

14 x 14 long or 85 x 85

Part A:

since the map is 14cm long, and the river is also 14 cm long, and each centimeter is equal to 85km, that means, =

14 x 85 = 1190km

<u><em>so the river is 1190km long</em></u>

<u />

Part B:

we can use just convert 765 into map cm to get answer,

sooo

765/85 = 9cm

SO THERE YOU HAVE IT:D
