-2y -2y
x=9-2y

2(9-2y) + 3y=14
18-4y+3y=14
-18 -18
-y=-4
y=4

x+2(4)=9

Given: Circle O with diameter LN and inscribed angle LMN<br> Prove: is a right angle.

Method 1.

Look at the picture 1.

We have:

$2\alpha=180^o\ \ \ \ |:2\\\\\alpha=90^o$

Picture 2.

$m\angle LMN=90^o$

------------------------------------------------------------------------------------------

Method 2. (Picture 3)

ΔLOM and ΔMON are isosceles triangles. Therefore the two angles opposite the legs are equal.

The sum of the internal angles in each triangle is 180°. Thereofre in ΔLMN we have:

$\alpha+\beta+\beta+\alpha=180^o\\\\2\alpha+2\beta=180^o\ \ \ |:2\\\\\alpha+\beta=90^o$

$m\angle LMN=\alpha+\beta\to m\angle LMN=90^o$

Answer: -6√2

Explanation: You’ll have to find where the original product can be rooted. 36 & 2. 36 is a perfect square, so it becomes 6.

Then 6 is on the outside, while two is inside.
Don’t forget the negative.
