Find the value of z. round to the nearest hundredth
Svetradugi [14.3K]

ANSWER

C. 64.29

EXPLANATION

The bigger right triangle is similar to the smaller right triangle, therefore

\frac{30}{14}  =  \frac{z}{30}

Multiply both sides by 30;

30 \times  \frac{30}{14}  =  \frac{z}{30}  \times 30

Simplify

z =  \frac{900}{14}

z = 64.28571429

We correct to the nearest hundredthth to obtain,

z = 64.29

The correct choice is C.
