<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
1 yard = 36 inches
1 inch = 2.54 cm = 0.0254 m
Hence:
1800 yard = 1800 yard * 36 in per yard = 64800 in
64800 in = 64800 in * 0.0254 m per in = 1645.92 m
Since there are 245 metres of wool in each ball of wool. hence:
Number of wool balls = 1645.92 m / 245 m = 6.72

In triangle ABC, BC = 29 units.
Given,
In Δ ABC, ∠A = 45°.
A perpendicular line segment traced from a triangle's vertex to its opposite side is said to be the triangle's altitude.
Let altitude meet AB on D.
So, AD = 20 units and DB = 21 units and ∠ADC = ∠BDC = 90°
In ΔADC,
tan A = DC/AD
tan 45° = DC/20
1 = DC/20
DC = 20 units
In ΔBDC,
BC² = BD² + DC² (Pythagorean Theorem)
= 21² + 20²
= 441 + 400
= 841
BC = √841
= 29
Hence, BC = 29 units.
