The sum of angles in any triangle is 180 degrees.

It is given <1+<3=154 degrees.

<1+<2+<3=180

Or <1+<3+<2=180

Substituting <1+<3=154 we have

154+<2=180

Subtracting 154 both sides <2=180-154

<2= 26 degrees

First option is right answer.

Two Angles are Supplementary when they add up to 180 degrees

Two Angles are complementary when they add up to 90 degrees

Given <1+<3 =154 So they are neither complementary or supplementary.

Answer:Neither

Find the value of Y<br> .....

Answer:

$y = 6 \sqrt{3} \: units$

Step-by-step explanation:

In order to find the value of y, first we need to find the length of the perpendicular dropped from one of the vertices of the triangle to its opposite side.

By geometric mean theorem:

Length of the perpendicular

$=\sqrt{9\times 3}$

$=\sqrt{27}\: units$

Next, by Pythagoras theorem:

${y}^{2} = {9}^{2} + {( \sqrt{27} )}^{2} \\ \\ {y}^{2} = 81 + 27 \\ \\ {y}^{2} = 108 \\ \\ y = \sqrt{108} \\ \\ y = \sqrt{36 \times 3} \\ \\ y = \sqrt{ {6}^{2} \times 3} \\ \\ y = 6 \sqrt{3} \: units$
