The answer is 108°
A regular pentagon has all its five sides equal and all five angles are also equal. Hence, the measure of each interior angle of a regular pentagon is given by the below formula. Measure of each interior angle = [(n – 2) × 180°]/n = 540°/5 = 108°.
Answer:
Step-by-step explanation:
a₁ = 1
a₂ = 2(1)+2 = 4
a₃ = 2(4)+3 = 11
a₄ = 2(11)+4 = 26
a₅ = 2(26)+5 = 57
a₆ = 2(57)+6 = 120
Answer:
29.1°
Step-by-step explanation:
Given that :
Riser, AB, Opposite = 10 cm
Thread, = AC, Adjacent = 18 cm
Angle of inclination, θ
Using trigonometry :
Tan θ = opposite / Adjacent = AB / AC
Tan θ = 10 / 18
θ = tan^-1(10/18)
θ = 29.055
Hence, angle of inclination is 29.1° (1 decimal place)
The cycle route for the triathlon is of 26 miles
A triathlon is an athletic event which involves races which involves of swimming, cycling, and running over various distances
According to the given data,
The most common triathlon distance for Bicycle route is 40 kilometers
1 mile = 1 .6 kilometer
Now we know that 1.6 kilometer is 1 mile
So we are required to convert kilometers of triathlon race into miles
Therefore, 40 kilometers in mile will be= 40/1.6 = 25 miles
Hence the cycle route is of 26 miles .
