1/4 + 5/12 = 3/12 + 5/12= 8/12 = 2/3

You must get the denominators the same so you multiply both 1 and 4 and you get 3/12. Then you add the two fractions and simplify it into 2/3

Find the length of side xz give your answers to 3 significant figures

aleksandrvk [35]

Answer:

XZ ≈ 14.4 cm

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos29° = $\frac{adjacent}{hypotenuse}$ = $\frac{ZY}{XZ}$ = $\frac{12.6}{XZ}$

Multiply both sides by XZ

XZ × cos29° = 12.6 ( divide both sides by cos29° )

XZ = $\frac{12.6}{cos29}$ ≈ 14. 4 ( to 3 sig. figs )
