Question

use the given measurements to solve each triangle. round to the nearest tenthplease help me book answer: r=11.6(angle P=40.3°) (angle R=50.7°)

Answer 1

Step-by-step explanation:

r = 11.6

p = 7.5

q = 9

∠R = 89 degrees

Using sine rule:

`\frac{r}{Sin\text{ R}}=\frac{p}{\text{Sin P}}`
`\begin{gathered} \frac{11.6}{\sin\text{ 89}\degree}=\frac{7.5}{\sin \text{ P}} \\ 11.6(\sin \text{ P) = 7.5(sin 89)} \end{gathered}`
