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

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
