Answer:
The area of a right-angle triangle is; Area = a x b / 2
Step-by-step explanation:
A right-angle triangle just like conventional triangle, has three sides.
The sides are labelled a, b and c. With a as the height of the triangle and b as the base and c as the slope or the hypotenuse.
The area of a triangle is: (base/2) x height
This is similar to the area of the right-angle triangle which is also half of the base multiplied by the height of the triangle, that is,
Area = ab / 2
Answer:
x = 13
∠WZX = 57°
Step-by-step explanation:
Because it is a rectangle, ∠XYZ is 90°
∠XZY + ∠YXZ = 90
(5x - 8) + (x + 20) = 90
simplify:
6x + 12 = 90
subtract 12 from each side
6x = 78
divide both sides by 6
x = 13
∠WZX is complimentary to angle (x + 20)
∠WZX = 90 - (13 + 20) = 57°
Answer:
Step-by-step explanation:
- Time Spent Sleeping=7 hours
- Time Spent Studying=
of the day - Time Spent Travelling= of the day
There are 24 hours in a day, therefore:
- Time Spent Studying= X 24 =6 Hours
- Time Spent Travelling= X 24 =6 Hours
The total hour used for sleeping, studying and travelling=7+6+6=19 hours
Hours used for other things=24-19=5 hours
Therefore, the fraction of the day used for other things=
Depends on the calculator you have at your disposal. If it's one of the TI-83 series, you can use the built-in 'fnint' function.
