Answer:

x = 10.19803903 meters

Step-by-step explanation:

First, you need to calculate the differences in the posts height.

8 - 6 = 2

Then you can use that to draw a right triangle and solve for the distance between the tops using Pythagorean theorem.

10² + 2² = x²

100 + 4 = x² --- solve

x² = 104 --- solve

x = 10.19803903 meters --- square root both sides

Answer:

C) 145 degrees

Step-by-step explanation:

angles 2 and 5 are same side interior angles, which means they're supplementary. (they add together to make 180)

using that, you can make the following equation:

(x is angle 2 to avoid confusion)

35 + x = 180

<em>subtract 35 from both sides</em>

x = 180 - 35

x = 145
