Bonjour, La consigne de mon DM de maths est la suivante :

Résoudre sin(x)cos(x) = 0 dans [0;2pi[

Je ne sais pas comment faire pouvez vous m'aider s'il vous plaît ?

Merci d'avance pour votre réponse

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.

these sign is used to tell weather the number is greater or less than the number   <   or >     but this sign means its equal =    

hope this you and
