The rate at which his pulse is increasing after 3 minutes is 9.5 beats per minute
<h3>How to determine the beat rate after 3 minutes?</h3>
The given graph shows the curve and the tangent.
From tangent line, we have the following points:
(x,y) = (3,119) and (1,100)
The beat rate (m) at this point is:
![m = \frac{y_2 -y_1}{x_2 -x_1}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7By_2%20-y_1%7D%7Bx_2%20-x_1%7D)
So, we have:
![m = \frac{100 - 119}{1 - 3}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B100%20-%20119%7D%7B1%20-%203%7D)
Evaluate the differences
![m = \frac{-19}{-2}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B-19%7D%7B-2%7D)
Evaluate the quotient
m = 9.5
Hence, the rate at which Sam's pulse is increasing after 3 minutes is 9.5 beats per minute

The answer to this equation would be x=4. Is that what u were asking?
You form a rhombus.
Draw an equilateral triangle, and then mirror it around its base. All the sides are clearly equal, because they are all sides of the same equilateral triangle.
Moreover, the top and bottom angle are 60°, because they are angles of an equilateral triangle, while the left and right angles are 120, because they're 60+60 angles.
