Answer:

<h3>Question 1 </h3>

<em>Adjacent angles are supplementary, opposite angles are equal</em>

62 + 5x + 3 = 180
5x = 180 - 65
5x = 115
x = 23

62 = 3y + 2
3y = 60
y = 20

<h3>Question 2</h3>

<em>Diagonals bisect each other</em>

4x = 3x + 7
x = 7

6y = 2y + 16
4y = 16
y = 4

Correct choice is A

Answer:

20 m

Step-by-step explanation:

Let the length of the perpendicular dropped from vertex C to segment AB be x

By geometric mean property:

$x = \sqrt{16 \times 9} \\ \\ x = \sqrt{144} \\ \\ x = 12 \: m \\ \\ By \: Pythagoras \: Theorem: \\ \\ Distance \: across \: the \: pond \\ \\ = \sqrt{ {16}^{2} + {12}^{2} } \\ \\ = \sqrt{256 + 144} \\ \\ = \sqrt{400} \\ \\ = 20 \: m$
