He made 4 round trips to visit his grandmother.
Further Explanation
Step 1
Amount of time he spent to get to his grandmother’s = 35 minutes and extra 4-minute walk (and can be expressed as 35 + 4)
= 35 + 4
= 39
Step 2
To complete a round trip, the amount of time he spent to his grandmother’s will be multiply by 2
Therefore,
= 39 x 2
= 78
Total amount of time of a round trip = 78
Step 3
Amount of time he spent on a trip to her apartment and back home = 5 hours and 12 minutes
To determine that, 5 hours will be added to 12 minutes
Therefore,
Since 1 hour = 60,
Then, (5 x 60) +12
= (5 x 60) + 12
= 300 + 12
= 312
Amount of time he spent on a trip to her apartment and back home = 312
Step 4
To determine how many round trip he made, the amount of time he spent on a trip to her apartment and back home (312) will be divided by the total amount of time of a round trip (78) i.e. 312 ÷ 78
= 312 ÷ 78
=
= 4
Therefore Juwan made a total of 4 round trips to his grandmother’s place.

of every angle.
When the angle is in a right triangle, they can be defined
like this:
Sine (sin) of the angle: (opposite leg) divided by (hypotenuse)
Cosine (cos) of the angle: (adjacent leg) divided by (hypotenuse)
Tangent (tan) of the angle: (opposite leg) divided by (adjacent leg)
Cotangent (cot) of the angle: (adjacent leg) divided by (opposite leg)
Secant (sec) of the angle: (hypotenuse) divided by (adjacent leg)
Cosecant of the angle: (hypotenuse) divided by (opposite leg).
The size of the right triangle doesn't matter, only the ratios of
pairs of sides. That will always be the same number for the
same angle, no matter how big or small the triangle is.
There's no easy way to calculate the numbers for an angle.
You just have to look them up, using tables in books, or online
(try 'cosine 29' on Google), or on most hand-calculators.
