Question

1.7 Determine the value of $$ 	heta $$, if $$ 	heta \in\left[0^{\circ} ; 90^{\circ}ight] $$, correct to 3 decimal places : 1.7.1 $$ 3 \cos 	heta=1,203 $$ $$ 1.7 .2 \quad 5 \cos x+2=4 $$ $$ 1.7 .3 \quad \frac{4}{3} \sin 	heta=\cos 37^{\circ} $$ $$ 1.7 .4 \quad 	an 3 	heta=6,345 $$ $$ 1.7 .5 \quad \frac{	an 	heta}{2}=2,5 $$ $$ 1.7 .6 \quad 2 \sin \left(	heta+15^{\circ}ight)=1,462 $$

Stephens Estrada · Accepted Answer

The values of $$ 	heta $$ for each equation are: 1. $$ 	heta \approx 66.157^\circ $$ 2. $$ x \approx 66.421^\circ $$ 3. $$ 	heta \approx 36.796^\circ $$ 4. $$ 	heta \approx 27.015^\circ $$ 5. $$ 	heta \approx 78.690^\circ $$ 6. $$ 	heta \approx 32.000^\circ $$
