![b = 2.7](https://tex.z-dn.net/?f=%20b%20%3D%202.7%20)
Step-by-step explanation:
Given:
< C = 53°
< B = 80°
a = 2
Required:
Find b
Solution:
The question given suggests we are given measures for a ∆.
To find side b, which corresponds to angle B, first, we'd find angle A, which corresponds to side a, then apply the Law of sines to find side b.
=> A = 180 - (53 + 80) = 47°
Law of Sines: ![\frac{a}{sin(A} = \frac{b}{sin(B}](https://tex.z-dn.net/?f=%20%5Cfrac%7Ba%7D%7Bsin%28A%7D%20%3D%20%5Cfrac%7Bb%7D%7Bsin%28B%7D%20)
Plug in the values into the formula
![\frac{2}{sin(47} = \frac{b}{sin(80}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%7D%7Bsin%2847%7D%20%3D%20%5Cfrac%7Bb%7D%7Bsin%2880%7D%20)
Cross multiply
![2*sin(80) = b*sin(47)](https://tex.z-dn.net/?f=%202%2Asin%2880%29%20%3D%20b%2Asin%2847%29%20)
Divide both sides by sin(47) to make b the subject of formula
![\frac{2*sin(80)}{sin(47} = b](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%2Asin%2880%29%7D%7Bsin%2847%7D%20%3D%20b%20)
![2.69 = b](https://tex.z-dn.net/?f=%202.69%20%3D%20b%20)
(nearest tenth)
Answer:
(2/3)x - (1/5) y = 10. to solve for x in terms of y: (2/3)x - (1/5) y = 10. (2/3)x = 10 + (1/5)y. x = (10 + (1/5)y)(3/2). x = 15 + 3/10 y. if y = 0; x = 15. to solve for y in terms ...
Step-by-step explanation:
It would be the 2nd one down and 3rd one up is the correct answer just look a little closer and you will see what i mean there ages are and and they have a 3o sec head start and they ran 60 yards in 30 sec.
