Answer:

x = 129

Step-by-step explanation:

Mathematically, the sum of interior angles of a polygon can be calculated using the formula;

(n-2)180

from the question given , n = 7 since the polygon has 7 sides

thus, we have it that

(7-2)180 = 5 * 180 = 900

Mathematically, by adding all the given interior angles, we can get the value of the total

We have this as;

900 = x + 131 + 119 + 125 + 133 + 125+ 138

900 = x + 771

x = 900-771

x = 129

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).
