Answer:

use Pythagoras theorem

Step-by-step explanation:

a^{2}  + b ^{2}  = c ^{2}  \\ a ^{2}    +  12 ^{2}  = 13 ^{2}  \\ a = 5

Answer:

a = 5

Step-by-step explanation:

a^2 + b^2 = c^2

Substitute

b = 12

c = 13

a^2 + 12^2 = 13^2

a^2 + 144 = 169

a^2 = 25

a = \sqrt{25} \\

a = 5

PLEASE HELP I AM DESPERATE!!!
Vilka [71]

Answer:

Statements:

m<b = 180 - m<a

m<c = 180 - m<d

m<b = m<c

180 - m<a = 180 - m<d

Reasons:

The measure of m<b is the angle of a straight line subtracted with m<a. The measure of m<c is the angle of a straight line subtracted with m<d. If m<a and m<d are equal, m<b and m<c are equal.

Step-by-step explanation:

We know, m<a = m<d

So, we need to prove m< b = m<c

Let's start by defining what b and c is

m<b + m<a = 180 This is because a straight line is 180 degrees

m<b = 180 - m<a

m<c + m<d = 180

m<c = 180 - m<d

With this, we can substitute in proof

m<b = m< c

180 - m<a = 180 - m<d

180 - m<a = 180 - m<a

Masteriza [31]

Answer:

The rate of change is 4.6 tickets/hour.

Step-by-step explanation:

The equation that represents the ticket sales is the equation of a line:

y = 4.6*x - 12.2

The equation of any given line can be writen by the following formula:

y = m*x + b

Where "m" is the slope of the line, or the rate of change, while b is the value for "y" when "x" is zero. Therefore in this case the rate of change is the number multiplying "x", so 4.6 tickets/hour.
