In △JKL, solve for x. <br><br> (A)74.89<br> (B)30.29<br> (C)38.16<br> (D)66.73
Stels [109]

ANSWER

(C)38.16

EXPLANATION

The acute angle given in the right triangle is 27°.

The side length adjacent to the 27° angle is 34 units.

The side length we want to find is x units, which is the hypotenuse of the right triangle.

We use the cosine ratio to obtain:

\cos(27 \degree)  =  \frac{adjacent}{hypotenuse}

\cos(27 \degree)  =  \frac{34}{x}

Solve for x,

x  =  \frac{34}{\cos(27 \degree)}

x = 38.16

to the nearest hundredth.

Describe a situation that models a linear pattern and then describe a situation that models a nonlinear pattern.
Nezavi [6.7K]
A linear pattern is when the points form a straight line. For example the following points follow a linear pattern: (0, 0), (1, 2), (2,4), (3,6). These points are all increasing by the same amount. X is increasing by 1 while Y increases by 2.
A non-linear pattern can pretty much be anything that doesn't follow an exact rule. Like: (0,1) (4,3), (6, 12), (7,9). These points would not form a straight line, it would just be a bunch of random points everywhere.

I hope that helps!
