Subtract the sum of -1 37 and - 43 from the sum of - 103 and 27

umka2103 [35]

Step-by-step explanation:

Hey, there!!

I hope you mean to subtract (-137) +(-43) from sum of -103 and 27.

First, add -103 + 27

$= - 103 + 27$

$= - 76$

{As ( minus + plus )= subtracts with sign which has greator value. }

now,

$( - 137) + ( - 43) = - 180$

{ minus + minus = add with minus sign}.

Now, subtracting -180 from -76.

=(-76) - (-180 )

Now, multiply the sign (- × -)= +

so, -180 becomes +180

= -76+180

= 104..... is answer.

Hope it helps...

Given :

On a number line, suppose the coordinate of A is 0, and AR = 15.

To Find :

the possible coordinates of the midpoint of AR.

Solution :

Their can be two points R which is at a distance of 15 units from the A .

One is -15 and other is 15.

Now, mid-point of A(0) and R(-15) is M (-7/2).

Also, mid-point of A(0) and R(15) is M (7/2).

Therefore, possible coordinates of the midpoint of AR is 7/2 , -7/2.

Hence, this is the required solution.

What is the exact value of tangent (negative StartFraction pi Over 3 EndFraction)?

salantis [7]

Answer:

tg (-60°) = -√3

Step-by-step explanation:

We can solve this, using a calculator, but I would like you to understand this problem without the use of that.

This is trigonometry, so first we need to know the value of pi in trigonometry.

The value of π is equals to 3.14 but in this case, we need to take the value of π in degrees. This value is 180°.

Now, the following step is replace this value into the expression:

tg (-180/3) = tg (-60°)

So the actual value we are looking for is tangent of 60°. Tangent can be calculated using the expression with the sin and cosine so:

tg = sin/cos

so to get the value of tg 60°:

tg 60° = sin 60° / cos 60°

The value of sin 60° = √3/2, while the value of cos 60° = 1/2, so replacing both values above, we can get the value of tg 60°:

tg 60° = (√3/2) / (1/2) both 2 gets cancel out so:

tg 60° = √3 / 1

tg 60° = √3

As we want tg(-60) the real value would be:

tg (-60°) = -√3

So the answer would be option 1.
