Answer:
2.5m
Step-by-step explanation:
50m divided by 20 = 2.5m
capacity of the stadium=23564
no.of seats occupied=3/4 of 23564
no.of people in the stadium=23564*3/4
=17673
Answer:
Step-by-step explanation:
A triangle whose sides are 5-12-13 is a right angle triangle because the sides form a Pythagoras triple. This means that
Hypotenuse² = opposite side² + adjacent side²
If hypotenuse = 13,
Opposite side = 12, then we can determine one acute angle by applying the sine trigonometric ratio
Sin θ = opposite side/adjacent side
Sin θ = 12/13 = 0.923
θ = Sin^-1(0.923) = 67.4°
The other acute angle is
90 - 67.4 = 22.6°
For 9-12-15 triangle
Sin θ = 12/15 = 0.8
θ = Sin^-1(0.8) = 53.1°
The other acute angle is
90 - 53.1 = 36.9°
For 13- 14-15 triangle,
Sin θ = 14/15 = 0.933
θ = Sin^-1(0.933) = 68.9°
The other acute angle is
90 - 68.9 = 21.1°
Another example would be 3-4-5
Sin θ = 4/5 = 0.933
θ = Sin^-1(0.8) = 53.1°
The other acute angle is
90 - 53.1 = 36.9°
Answer:
15 inches tall
Step-by-step explanation:
To solve I would set up a ratio to visualize the question.
x in : 90 ft
1 in : 6ft
Then divide... 90 ÷ 6 = 15 ( this is the inches in the ratio that compares to 90 ft).
