The area of the triangle ABC is 207.5 square units.
Explanation:
The measurements of the sides of the triangle are
,
and ![m\angle A=65^{\circ}](https://tex.z-dn.net/?f=m%5Cangle%20A%3D65%5E%7B%5Ccirc%7D)
We need to determine the area of the triangle ABC.
<u>Area of the triangle:</u>
The area of the triangle can be determined using the formula,
![{Area}=\frac{1}{2} b c \sin A](https://tex.z-dn.net/?f=%7BArea%7D%3D%5Cfrac%7B1%7D%7B2%7D%20b%20c%20%5Csin%20A)
where
,
and ![m\angle A=65^{\circ}](https://tex.z-dn.net/?f=m%5Cangle%20A%3D65%5E%7B%5Ccirc%7D)
Substituting these values in the above formula, we get,
![{Area}=\frac{1}{2}(19)(24) \sin 65^{\circ}](https://tex.z-dn.net/?f=%7BArea%7D%3D%5Cfrac%7B1%7D%7B2%7D%2819%29%2824%29%20%20%5Csin%2065%5E%7B%5Ccirc%7D)
Simplifying the values, we get,
![{Area}=\frac{1}{2}(456) (0.91)](https://tex.z-dn.net/?f=%7BArea%7D%3D%5Cfrac%7B1%7D%7B2%7D%28456%29%20%280.91%29)
![{Area}=\frac{1}{2}(414.96)](https://tex.z-dn.net/?f=%7BArea%7D%3D%5Cfrac%7B1%7D%7B2%7D%28414.96%29)
![{Area}=207.48](https://tex.z-dn.net/?f=%7BArea%7D%3D207.48)
Rounding off to the nearest tenth, we get,
Thus, the area of the triangle ABC is 207.5 square units.

roulette consists in placing a small ball in a roulette wheel, Probability (Roulette ball not landing on red) = 10 / 19
The probability of an event can be calculated by probability formula by simply dividing the favorable number of outcomes by the total number of possible outcomes
Given:
Number of total slots = 38
Number of red slots = 18
Number of black slots = 18
Number of green slots = 2
Find:
Probability (Roulette ball not landing on red)
Computation:
Probability (Roulette ball not landing on red) = 1 - Probability (Roulette ball landing on red)
Probability (Roulette ball not landing on red) = 1 - (18 / 38)
Probability (Roulette ball not landing on red) = 20 / 38
Probability (Roulette ball not landing on red) = 10 / 19
