It's the one in the top right corner. Since the inequality says 'greater than or equal to' the line has to be bold and the shaded area has to be above the line. Hope this helped!

I really need help I don’t understand how to do this
krek1111 [17]

Answer:

Step-by-step explanation:

Remark

The way this is worded, it sounds like it is a horizontal distance. However by the marking it looks like they want the hypotenuse. Life can be very confusing sometimes.

The angle of the triangle that you need to know is the one on the right. The line of sight line is parallel to the base of the triangle. So the angle on the right is 8 degrees by the Z theorem.

Solution

Sin(8) = 1817 / x           Multiply both sides by x

x*sin(8) = 1817             Divide by sin(8)

x = 1817/sin(8)

sin(8) = 0.1392

x = 1817/0.1392

x = 13055.7

Note

Watch how you do this. I would put it into your calculator as

1817

÷

sin(8)

=

If you use the rounded answer I gave for sin(8), you might get it wrong. This is a big distance and you should just use the exact number you get for sin(8).

The area of a isosceles trapezoid height of 8 base of 10 base of 15
ikadub [295]

Answer:

A = 100 un^{2}

Step-by-step explanation:

You have to use the area of a trapezoid formula:

A = \frac{h}{2}(a + b)

Now, substitute the values of the height and the bases:

A = \frac{8}{2}(10 + 15)

Finally, simplify the equation to solve for the area:

A = 4(25)

A = 100 un^{2}
