Answer:

Sides in descending order: YZ > ZX > XY

Step-by-step explanation:

Sum of all angles of triangle = 180

104 +52 + ∠Z = 180

156 + ∠Z = 180

∠Z = 180 - 156

Z = 24

The sides opposite to the biggest is the longest side.

Angles in descending order: ∠X > ∠Y > ∠Z

<h3>Sides in descending order: YZ > ZX > XY</h3>

Help!!!!

____ [38]

This is a relatively easy question if you know a couple things, so let me walk you through this step by step ok?

<em>Answer: 115°</em>

<h3>Sum of interior angles of a pentagon: 540°</h3>

Now with that said:

Your first step is to add all of the interior angles together, and then subtract it from the total sum of the interior angles of the shape that your working with.

If you don't know what the sum of all of the interior angles are for the shape you are working with, you can easily look it up on google to be sure.

<em>If you have anymore questions, </em>Don't be afraid to ask! I'm always glad to help, also if I am wrong please let me know and I promise I will come back and rework my math.

<h2>Thanks!</h2>

Answer:

$x < - \frac{5}{13}$

$x \geqslant - \frac{1}{5}$

Step-by-step explanation:

↷

$- \frac{13}{16}x + \frac{3}{8} < \frac{11}{16} \\ \frac{ \: \: \: \: \: \: \: \: \: \: \: \: - \frac{3}{8 } < - \frac{3}{8} }{ \frac{ - \frac{13}{16}x }{ - \frac{13}{16} } < \: \: \: \frac{ \frac { 5}{16} }{ - \frac{ 13}{16} } } \\ \\ x < \frac{ - 5}{ \: 13}$

↷

$\frac{1}{3} \geqslant \frac{2}{9} - \frac{5}{9} x \\ \frac{ - \frac{ 2}{9} \geqslant - \frac{2}{9} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: }{ \frac{ \: \: \: \frac{1}{9}x }{ - \frac{ 5}{9} } \geqslant \frac{ - \frac{5}{9} }{ - \frac{5}{9} } } \\ \\ x \geqslant - \frac{1}{5}$

SURFACE AREA PLEASE HELP

disa [49]

Answer:

486 yd^2

Step-by-step explanation:

Surface area is just finding the area of each face in a figure and adding it all up.

For the surface area of a cube, use this formula:

(a^2) 6

(a is the side length) a^2 is the area of one face of a cube, then multiply it by 6 since there are 6 faces on a cube.

Use formula with given dimensions:

(9^2) 6 = 486

Surface area is measured in square yards

(yards in this case)

Therefore, the surface area of the cube is 486 yd^2

Hope this helps!
