The question is incomplete as the figure of the 3 triangles is not given.
However, I'll give a general tip on how to identify the types of triangles.
1. Right-angled
When one of the three angles of the triangle is 90 degrees, then that triangle is a right-angled triangle
2. Acute triangle
When all the three angles of the triangle are less than 90 degrees, then that triangle is an acute triangle
3. Obtuse triangle
When one of the three angles of the triangle is greater than 90 degrees, then that triangle is an obtuse triangle.
<em>See attachment for illustration</em>
V^2 = u^2 - 2gh; where v is the final speed, u is the initial speed, g = 9.8 m/s = 0.54 ft/min is the accerelation due to gravity, h = height.
At the maximum height, the final speed is 0.
u^2 = 2gh = 2 x 0.54 x 36 = 38.58
u = sqrt(38.58) = 6.21 ft/min
Therefore, the stne should be thrown with 6.21 ft/min
Relative extrema occur where the derivative is zero (at least for your polynomial function).
So taking the derivative we get
<span>20<span>x3</span>−3<span>x2</span>+6=0

This is a 3rd degree equation, now if we are working with complex numbers this equation is guaranteed to have 3 solutions by the fundamental theorem of algebra. But the number of real roots are 1 which can be found out by using Descartes' rule of signs. So the maximum number of relative extrema are 1.</span>

Hope this helps
Answer:
26
Step-by-step explanation:
add both expressions to equal 90 (bc of the right angle)- x+11+2x+1=90
when you solve, you get x=26
