Answer:
122˚
Step-by-step explanation:
1. Visual estimation
∠BXD is obtuse so ∠BXD > 90˚
Let’s designate the number of banana splits sold as x. That means the number of sundaes sold is x + 8.
Now if we put this into an equation, also keeping in mind their costs, we get:
3(x) + 2(x + 8) = 156
Now to solve for x:
3x + 2(x + 8) = 156
3x + 2x + 16 = 156
5x = 140
x = 28
That means you’ve sold 28 banana splits and 36 sundaes! :)
X+y=15
2x+3y=37
15-x=y
2x+3(15-x)=37
2x+(45-3x)=37
2x-3x+45=37
-1x=-8
x=8
x is the amount of bikes, so there are 8 bikes. 8x2=16.
37-16=21
21/3=7
There are 7 tricycles.

<h3>
Pythagoras theorem</h3>
Pythagoras theorem is used to show the relationship between the sides of a right angle triangle. It is given by:
Hypotenuse² = Adjacent side² + Opposite side²
From the diagram, one box is one unit, using Pythagoras theorem:
5² = 3² + 4²
25 = 9 + 16
25 = 25
The diagram shows how Pythagoras theorem is applied to a right angled triangle.
