Aiuto per favore Negli anni 80 del secolo scorso un disco di musica classica aveva il diametro di 30 cm mentre un moderno CD al diametro di circa 12 cm qual è il rapporto tra le aree di due cerchi che costruiscono i suddetti dischi

c. 65°

step-by-step explanation:

we are given a triangle with two known angles, 62° and 53°, while the third angle x is unknown and we are to find its value.

we know that the sum of angles in a triangle is equal to a total of 180 degrees. so we can write it as:

x + 62° + 53° = 180°

solving to find the value of x:

x = 180 - (62 + 53) = 65°

therefore, the value of x in this triangle is 65°.

typically if you want , you would actually put questions here for us to you. but hey, that's just me. maybe someone will magically answer the questions for you without knowing what they are.

answer: 8d

step-by-step explanation:

45+5= 50+5=55+5=60
