In an oblique triangle, the side lengths are 16 cm, 26 cm, and x cm. The angle opposite side x is 63o. To the nearest cm, find the value of x.

 x = 23.5 cm

Step-by-step explanation:

Use the law of Cosines: a² = b² + c² - 2bc · cos A

Given: A = 63°, a = x, b = 16, c = 26

x² = (16)² + (26)² - 2(16)(26) · cos(63°)

x² = 554.1316

x = 23.54

x ≈ 23.5

answer: 457.14

step-by-step explanation:

205 - 45 = 160

160 / .35 = 457.142857

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
