We conclude that the solution to the given linear equation is x = 15/13.

<h3>How to solve that equation for x?</h3>

Here we have the linear equation:

13x - 4 = 11

And we want to solve this for x. To do so, we need to isolate x in one side of the equation.

We can start by adding 4 in both sides, so we get:

13x - 4 + 4 = 11 + 4

13x = 15

Now we can divide both sides by 13, so we get:

13x/3 = 15/13

x = 15/13

We conclude that the solution to the given linear equation is x = 15/13.

Which expression is equivalent to i 233?<br> a)1<br> b)–1<br> c)i<br> d)–i

Aneli [31]

We have to find the value of the expression $i^{233}$

We know that the below values.

$i^2=-1\\i^4=1$

Hence, in order to find the value of the given expression, we can first rewrite it in terms of $i^4$

$i^{233}=(i^4)^{58}\cdot i$

Now, we know that $i^4=1$

Hence, we have

$i^{233}=(1)^{58}\cdot i$

$i^{233}=1\cdot i$

$i^{233}=i$

C is the correct option.

What is the area of △ABC?

kirza4 [7]

Answer:
Area = 492.4 m²

Explanation:
The area of the triangle can be calculated using the side-angle-side method as follows:
Area = 0.5 * first side * second side * sin(angle included between these two sides)

This rule is illustrated in the attached image.

Now, we have:
AB = 40 m
BC = 25 m
angle B which is the angle included between AB and BC = 80 degrees

The given angle is included between the two given sides, therefore, we can apply the above rule to get the area.
Area of triangle = 0.5*40*25*sin(80)
Area of triangle = 492.4 m²

Hope this helps :)
