By Pythagoreans' theorem,
7.5² = l² × b²
56.25 = l² × b²
Since l = b
56.25 ÷ 2
= l²/b²
= 28.125 mm
∴ l = √28.125
= 5.3033 mm
Area of square
= √28.125 × √28.125
= 28.125 mm²
≈ 28.1 mm² (3s.f.)
Circumference= pi × d
So
d= circumference/pi
So to find out the diameter, just do 56.52/pi= 17.99mm (2 d.p.)
We can form a system of equations:
x*y=90
and
x=2y+3.
Solving gives dimensions of 15 feet by 6 feet.
For this case we have the following trigonometric relationship:
cos (y) = 8/13
Clearing the value of and we have:
y = Acos (8/13)
Calculating the angle we have:
y = 52.02012756 degrees
Rounding off we have:
y = 52.02 degrees
Answer:
the measure of angle and is:
y = 52.02 degrees
No, it multiplies by -1 each time. Arithmetic sequences add or subtract by a constant number
