Answer:
∠ K = 35° and ∠ L = 105°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
let ∠ K = x then ∠ L = 3x
Sum the angles and equate to 180
3x + x + 40 = 180, that is
4x + 40 = 180 ( subtract 40 from both sides )
4x = 140 ( divide both sides by 4 )
x = 35
Thus
∠ K = 35° and ∠ K = 3x = 3 × 35 = 105°
Answer:
315
Step-by-step explanation:
We are told in the question that each fret marker is in the shape of a parallelogram
The area of a parallelogram is given as
Base × Height.
Each of the bottoms of the fret markers has the following values
Base = 52.5mm
Height =6 mm
The area of each of the bottom fret markers
= Base × Height
= 52.5 × 6
= 315
Therefore, the area of each of the bottom fret markers without unit is 315
