Answer:

a = 13.8

(missing length of triangle = 13.8 meters)

Step-by-step explanation:

The side lengths of a triangle can be related using the Pythagorean Theorem;

a² + b² = c²

where

a = one side length

b = other side length

c = hypotenuse (long side --across from 90° angle)

So, by plugging our values into the Pythagorean Theorem, we can solve for a:

a = unknown

b = 18.4

c = 23

a² + b² = c²

a² + 18.4² = 23²

a² + 338.56 = 539

    - 338.56   - 338.56       {subtract 338.56 from both sides to isolate a}

a² = 190.44

√a² = √190.44

a = 13.8

so, the missing length of the triangle is 13.8 m

hope this helps!!

Answer:

13.8

Step-by-step explanation:

a^2 + b^2 = c^2

a^2 + 18.4^2 = 23^2

a^2 + 338.56 = 529

a^2 = 190.44

a = 13.8

The missing length is 13.8 meters

hope this was helpful :)

What is the solution to the inequality x^2 >64
Gnom [1K]

Answer:

see explanation

Step-by-step explanation:

Consider

x² = 64 ( take the square root of both sides )

x = 8 , x = - 8 ← are the critical points

Then for x² > 64

x < - 8 or x > 8

Answer:

174

Step-by-step explanation:

Given

132, 145, 97, 112, 128, 82

Required

Estimate amount of students in an art class

This is calculated by obtaining the mean of the given data

Mean = \frac{\sum x}{n}

Where n is the number of observations

So;  n = 6

Mean = \frac{132+ 145+ 97+ 112+  128+  82}{6}

Mean = \frac{696}{6}

Mean = 174.0

<em>Hence, the estimated number of students is 174</em>

Draw a line representing the "rise" and a line representing the "run" of the line. State the slope of the line in simplest form.
stealth61 [152]

Answer:

See attachment showing the rise and run

Slope = 1

Step-by-step explanation:

In the diagram attached below, the rise is represented by the blue line, while the run is represented by the red line.

Rise = 4 units

Run = 4 units

It's a positive slope because the line slopes upwards from left to right

Slope = rise/run = 4/4

Slope = 1
