Find the adjacent side of the triangle ...
7² + x² = 25²
x² = 25² - 7²
x² = 576
x = 24
The adjacent side of the triangle is 24
Given that sin A =
![\frac{7}{25}](https://tex.z-dn.net/?f=%20%5Cfrac%7B7%7D%7B25%7D%20)
Since sin A =
![\frac{o}{h}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bo%7D%7Bh%7D%20)
We can conclude that o = 7 and h = 25
cos A =
cos A =
1/4, because in 1/3, you would only need 3 parts to get one whole, but in 1/4, you would need 4 parts to get a whole.
60 = 2x - 16
2x= 16+ 60 = 76
76 / 2 = 38
Hope this helps!
Best of luck
Answer:
x = 5/2
Step-by-step explanation:
We can use cross products to solve this equation
x/3 = 5/6
Multiply
x*6 = 3*5
6x = 15
Divide each side by 6
6x/6 = 15/6
Simplify
x = 5/2
