Answer: Okay, what's the question?
Step-by-step explanation:
Answer:
Cos A = (√51)/ 10
Step-by-step explanation:
sin is opposite/hypothenuse
cos is adjacent/hypothenuse
Pythagorus theorem says that c² = a² + b²
10² = 7² + b²
b² = 100 - 49
b = ±√51
It doesn't make sense for a length to be a minus number therefore, we will use +√51.
Cos A = (√51)/ 10
Tell me if I am wrong.

20 because of the whole is 40 and the shaded part is by 20 you just take half of 40 and you get 20
2860 times .12 equals $343.20
Answer:
Step-by-step explanation:
11x - 2° = 75° ( being corresponding angles )
11x = 75° + 2°
11x = 77°
x = 77°/ 11
x = 7°
