Angle 2, angle 3 and angle 4 will measure 60°

Step-by-step explanation:

From the figure attached,

'l' and 'm' are parallel lines and 't' is the transverse line.

m∠1 = m∠2 = 60° [Vertical angles]

m∠1 = m∠3 = 60° [Corresponding angles]

m∠1 = m∠4 = 60° [Alternate exterior angles]

Therefore, angle 2, angle 3 and angle 4 will measure the same as angle 1.

step-by-step explanation:

the true ones are a b and d

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours
