Answer:
Step-by-step explanation:
The side opposite the 30 degree angle is always half of the hypotenuse in the 30,60,90 triangle so
h=2(6)
h=12
The length of the altitude AD is 12 units.
<h3>How to find the height of a triangle?</h3>
The height of the triangle can be found as follows:
We have to find an angle using cosine law before we can find the height.
Therefore,
20² = 13² + 21² - 2 × 21 × 13 cos B
400 = 169 + 441 - 546 cos B
400 - 610 = - 546 cos B
-210 = - 546 cos B
cos B = -210 / -546
cos B = 0.38461538461
B = cos⁻¹ 0.38461538461
B = 67.3810899783
B = 67.38°
Hence,
sin 67.38° = opposite / hypotenuse
sin 67.38° = AD / 13
cross multiply
AD = 13 sin 67.38°
AD = 11.9999882145
AD = 12 units

Answer:
1302 males & 3038 females
Step-by-step explanation:
3x + 7x = 4340
10x = 4340
x = 434
3(434) = 1302 males
7(434) = 3038 females
