Answer:
150
Step-by-step explanation:
If you draw a diagram, this will be a rectangle and the line across cuts it into a right triangle, with a base of 120 and a height of 90. The need to know the length of the hypotenuse of the triangle, so we can use the pythagorean theorem.
90^2 + 120^2 = c^2
c=150
The 7 unit side and the unit 10
since they are both perpendicular to the same 8 unit side
:)
To find the measure of angle A set up a trig function, sin, cos otr tan.
Since all sides are know any ratio will work.
Sin A = opposite/hypotenuse
Sin A = 80/82
Sin-1 (80/82) = angle A
A= 77.32 degrees
If he chews 4 pieces of gum a day that is 28 a week so if you need 28 and gum comes in packs of 7 28/7 is 4 so he will need 4 boxes of gum a week or 18 packs a month or 213 a year
