Angela took 56 minutes to take her history test brian took 70% of the time that it took angela to complete the test . How long did it take brian to take the history test

39.2 minutes

Step-by-step explanation:

Angela used 56minutes. Brain used 70% of Angela's time which will be 70% of 56.

70/100 × 56 = 39.2 minutes.

Therefore, Brian used 39.2 minutes for the test.

39.2 minutes (39 minutes and 12 seconds)

Step-by-step explanation:

We know that Brian took 70% of the time that Angela took to complete the test, so to find how long Brian took to take the history test, we need to multiply the percentage (70%) of time from Angela's time (56 minutes):

70% of 56 = (70/100) * 56 = 0.7 * 56 = 39.2

Brian took 39.2 minutes (39 minutes and 12 seconds) to complete the history test.

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.
