The answer is c man hope this helped
Answer:
10 square2
36 + 64 = 100. In other words, 6² + 8² = 10²
X is minus 30 over 7
So you can cross multiply and multiply the values.
Then you can solve it like a normal equation
Answer:
The expression is
![BC=\frac{3}{sin(38^o)}sin(66^o)](https://tex.z-dn.net/?f=BC%3D%5Cfrac%7B3%7D%7Bsin%2838%5Eo%29%7Dsin%2866%5Eo%29)
![BC=4.45\ units](https://tex.z-dn.net/?f=BC%3D4.45%5C%20units)
Step-by-step explanation:
we know that
In the triangle ABC
Applying the law of sines
![\frac{AB}{sin(C)}=\frac{BC}{sin(A)}](https://tex.z-dn.net/?f=%5Cfrac%7BAB%7D%7Bsin%28C%29%7D%3D%5Cfrac%7BBC%7D%7Bsin%28A%29%7D)
we have
![AB=3\ units\\C=38^o\\A=66^o](https://tex.z-dn.net/?f=AB%3D3%5C%20units%5C%5CC%3D38%5Eo%5C%5CA%3D66%5Eo)
substitute the given values
![\frac{3}{sin(38^o)}=\frac{BC}{sin(66^o)}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7Bsin%2838%5Eo%29%7D%3D%5Cfrac%7BBC%7D%7Bsin%2866%5Eo%29%7D)
Solve for BC
![BC=\frac{3}{sin(38^o)}sin(66^o)](https://tex.z-dn.net/?f=BC%3D%5Cfrac%7B3%7D%7Bsin%2838%5Eo%29%7Dsin%2866%5Eo%29)
![BC=4.45\ units](https://tex.z-dn.net/?f=BC%3D4.45%5C%20units)
