Answer:
90 degree
Step-by-step explanation:
∠ 1 , ∠2 and ∠3 are three interior angles of a triangle so the sum of these three angles are 180°
From the figure, ∠1 is a right angle means m∠1=90°
m∠1+m∠2+m∠3=180°
m∠2+m∠3=180°-m∠1
m∠2+m∠3=180°-90°
m∠2+m∠3=90°
Hey there! Do you have a image for this problem so we can help you? :)
Subtract the volume of the inside diameter from the volume of the outside diameter and then multiply that by the density.
Volume of outside:
PI x 1.8^2 x 3.9 = 39.67704 cubic cm
Volume of inside:
PI x 1.35^2 x 3.9 = 22.318335 cubic cm
Difference: 39.67704 - 22.318335 = 17.358705 cubic cm.
Mass = 17.358705 x 8 = 138.86964 grams. Round the answer as needed.
