Question

#3 1Let ZD be an acute angle such that sin D = 0.75. Use a calculator to approximate the measure of ZD to the nearest tenthof a degree.m/D

Answer 1

48.6 degrees

EXPLANATION :

From the problem, we have :

`\sin D=0.75`

Take the arcsin of the equation :

`\begin{gathered} \arcsin(\sin D)=\arcsin(0.75) \\ D=48.59\sim48.6 \end{gathered}`
