Answer:
second box is 5 and third bo is 40 and forth box is 0.25 I think! Sorry if it’s wrong!
Step-by-step explanation:
you divide them all by four.
From the law of sines, we have
![l = h\sin(\theta) = h\cos(\alpha)](https://tex.z-dn.net/?f=%20l%20%3D%20h%5Csin%28%5Ctheta%29%20%3D%20h%5Ccos%28%5Calpha%29)
where
is the leg we're interested in,
is the hypothenuse,
is the angle opposite to
, and
is the angle between
and
.
So, in the first case, we can use
![x = 15\sin(35) \approx 8.6](https://tex.z-dn.net/?f=%20x%20%3D%2015%5Csin%2835%29%20%5Capprox%208.6%20)
And in the second excercise, we use
![x = 11\cos(44) \approx 7.6](https://tex.z-dn.net/?f=%20x%20%3D%2011%5Ccos%2844%29%20%5Capprox%207.6%20)
Answer: $264
Steps:
1. Change 20% into a decimal. by moving decimal two places to the left.
.20
2. 330 * .20 = 66
20% of 330 is 66 meaning $66 will be discounted from the tv’s original price.
3. 330 - 66 = 264
330 - original price of tv
20% (.20) - discount
264 - price of tv after discount
Equation used to solve: 330 - (330 * .20)
Here is the answer
4(2a+3b)(2a-3b)
Answer:
x = 10
Step-by-step explanation:
3x + 14 + 4x + 6 = 90
7x + 20 = 90
90 - 20 = 70
70 / 7 = 10
x = 10
