Answer:

-11

Step-by-step explanation:

-3-8 can also be written as (-3) + (-8). When the brackets are opened it becomes -3-8.

To determine, whether to add or subtract the two numbers, there is a simple rule:-

1)Minus and Minus makes plus

2)Minus and plus makes Minus

3)plus and Minus makes Minus

4)plus and plus makes plus

Now to determine which sign to be put on the number, there is another rule:-

1) Put the sign of the greater number

Now in this case -3-8.

As you can see there are 2 negative numbers so the first rule is applied and they are added. So that makes 11. The largest number among the 2 is 8 and the sign of 8 is negative and hence our answer is negative that is -11

Hope this helps.

Dovator [93]

Answer:

D. no solution

Step-by-step explanation:

h-z=3(1)

h=3+z(minus z from both side)

put in the second equation

-3h,+3z=6(2)

-3(3+z)+3z=6

-9-3z+3z=6

-9=6( not true)

so the equation doesn't have a solution.

In order to apply the law of sines to find the length of the side of a triangle, it is enough to know which of the following?
larisa86 [58]

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.
